Alright — I’ll now write out all 50 questions for you here in text form before
turning them into any PDF.
They’ll be structured as:
---
Section A – Chemistry (25 questions)
(University level, physical, inorganic, organic, analytical, environmental)
1. Thermodynamics: Derive the expression for the Gibbs free energy change
in terms of enthalpy and entropy for a chemical reaction.
2. Chemical Kinetics: A first-order reaction has a rate constant of 3.2 × 10⁻³
s⁻¹. Calculate the half-life.
3. Equilibrium: For the reaction N₂(g) + 3H₂(g) ⇌ 2NH₃(g), Kp = 4.3 × 10⁻⁵ at
400°C. Discuss the effect of increasing pressure on the yield.
4. Quantum Chemistry: State and explain the significance of the principal
quantum number, n, in the hydrogen atom.
, 5. Solid State Chemistry: Differentiate between FCC and BCC crystal
structures in terms of coordination number, packing efficiency, and
examples.
6. Coordination Chemistry: Write the IUPAC name of [Co(NH₃)₆]Cl₃ and state
its oxidation state.
7. Acid-Base Chemistry: Explain the concept of Lewis acids and bases with
two examples each.
8. Electrochemistry: A Daniell cell has E° = 1.10 V. Calculate the equilibrium
constant for the reaction at 298 K.
9. Organic Chemistry: Predict the major product of the reaction between
propanone and hydrogen cyanide in the presence of NaOH.
10. Stereochemistry: Explain why 2-butanol is optically active while 2-
propanol is not.
11. Spectroscopy: Describe how IR spectroscopy can be used to identify
carbonyl compounds.
