Physical Chemistry flashcards for CSIR NET Chemical Sciences
19 of 58 cards from the Physical Chemistry deck — real questions with worked answers.
What does the time-independent Schrödinger equation state, and what is its compact operator form?
It states Ĥψ = Eψ, where Ĥ is the Hamiltonian operator (kinetic + potential energy), ψ is the wavefunction (eigenfunction), and E is the energy eigenvalue. It is the central equation of quantum mechanics for stationary states.
In quantum mechanics, what is the physical interpretation of |ψ|² (the Born interpretation)?
|ψ|² gives the probability density of finding the particle at a given point. |ψ|² dτ is the probability of finding the particle in the volume element dτ. ψ must be normalized so that ∫|ψ|² dτ = 1.
State the Heisenberg uncertainty principle for position and momentum.
Δx · Δp ≥ ħ/2, where ħ = h/2π. The position and momentum of a particle cannot be simultaneously measured with arbitrary precision; the more precisely one is known, the less precisely the other can be known.
What are the conditions for a wavefunction to be 'well-behaved' (acceptable) in quantum mechanics?
It must be single-valued, continuous, finite (and have continuous first derivative), and square-integrable (normalizable). These ensure |ψ|² is a valid probability density.
What is the energy expression for a particle in a 1-D box of length L?
Eₙ = n²h²/(8mL²), where n = 1, 2, 3,… (n ≠ 0), m is the particle mass and L the box length. Energy is quantized and the lowest level (n=1) has nonzero zero-point energy.
For the hydrogen atom, what is the formula for the energy of the nth level (in eV)?
Eₙ = −13.6/n² eV (n = 1, 2, 3,…). Energy is negative (bound states) and depends only on the principal quantum number n in the simple Bohr/Schrödinger treatment.
What is the Bohr radius (a₀) and its approximate value?
The Bohr radius is the most probable distance of the electron from the nucleus in the hydrogen 1s ground state, a₀ = 4πε₀ħ²/(m_e e²) ≈ 0.529 Å (52.9 pm).
What are the four quantum numbers and the property each describes?
Principal (n): energy/shell size; Azimuthal/angular (l): subshell shape (0 to n−1); Magnetic (mₗ): orbital orientation (−l to +l); Spin (mₛ): electron spin (+½ or −½).
How many radial nodes and angular nodes does an orbital have in terms of n and l?
Angular (nodal planes) = l; Radial nodes = n − l − 1; Total nodes = n − 1.
State the Pauli exclusion principle.
No two electrons in an atom can have the same set of all four quantum numbers. Equivalently, an orbital can hold at most two electrons, and they must have opposite spins.
What is the variation theorem (variation method) used for in quantum chemistry?
It states that the energy calculated from any trial wavefunction is always greater than or equal to the true ground-state energy (E_trial ≥ E₀). Minimizing E_trial with respect to parameters gives the best approximation to the ground state.
What does perturbation theory do as an approximation method?
It treats the Hamiltonian as Ĥ = Ĥ⁰ + Ĥ′, where Ĥ⁰ is exactly solvable and Ĥ′ is a small perturbation. Energy and wavefunction corrections are expressed as a series; the first-order energy correction is E⁽¹⁾ = ∫ψ⁰* Ĥ′ ψ⁰ dτ.
Define the order and molecularity of a reaction and give a key distinction.
Order = sum of exponents of concentration terms in the experimentally determined rate law (can be fractional/zero). Molecularity = number of species in an elementary step (always a positive whole number). Order is experimental; molecularity is theoretical per elementary step.
Give the integrated rate law and half-life for a first-order reaction.
Integrated: ln[A] = ln[A]₀ − kt (or k = (2.303/t) log([A]₀/[A])). Half-life: t₁/₂ = 0.693/k, which is independent of initial concentration.
Give the integrated rate law and half-life for a second-order reaction (single reactant).
Integrated: 1/[A] = 1/[A]₀ + kt. Half-life: t₁/₂ = 1/(k[A]₀), inversely proportional to initial concentration. Units of k are M⁻¹ s⁻¹.
For a zero-order reaction, what is the integrated rate law, half-life, and units of k?
Integrated: [A] = [A]₀ − kt. Half-life: t₁/₂ = [A]₀/(2k). Units of k: M s⁻¹ (concentration/time).
State the Arrhenius equation and the meaning of each term.
k = A·e^(−Eₐ/RT), where k = rate constant, A = pre-exponential (frequency) factor, Eₐ = activation energy, R = gas constant, T = absolute temperature. Linear form: ln k = ln A − Eₐ/RT.
What is the steady-state approximation in chemical kinetics?
It assumes the concentration of a reactive intermediate remains essentially constant over time (d[intermediate]/dt ≈ 0). This lets you express the intermediate's concentration in terms of reactants and derive the overall rate law.
What is the rate-determining step of a reaction mechanism?
The slowest elementary step in a multi-step mechanism; it governs the overall reaction rate, and the experimental rate law usually reflects the species involved up to and including this step.
Planning Physical Chemistry for CSIR NET Chemical Sciences
Physical Chemistry is about 29% of the CSIR NET Chemical Sciences syllabus by topic count — 29 of 99 topics, spread over 8 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 20 hours.
The heaviest chapters are Quantum Chemistry (4 topics), Thermodynamics (4 topics), Electrochemistry (4 topics) . Front-load those while your energy is high; the short chapters are better revision filler later.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
