MODULE - A (Physical Chemistry)
(Marks: 15)
1. Answer any five questions from the following: $1 \times 5 = 5$
a) State the Second Law of Thermodynamics in terms of entropy. b) Define the term "Gibbs Free Energy". What is the condition for spontaneity in terms of Gibbs free energy at constant temperature and pressure? c) What is meant by "order of a reaction"? Can a reaction have a fractional order? d) State the difference between a "reversible" and an "irreversible" process. e) Define the term "phase" as used in the Phase Rule. f) Write the expression for the rate constant of a first-order reaction. g) What is the significance of the term 'collision frequency' in the collision theory of reaction rates? Syllabus topics commonly covered
2. Answer any two questions from the following: $5 \times 2 = 10$
a) Derive the Gibbs-Helmholtz equation. Explain how the change in free energy helps predict the stability of a phase. b) Derive the integrated rate law for a first-order reaction. Show that the half-life of a first-order reaction is independent of the initial concentration of the reactant. c) Draw and explain the Phase Diagram of Water. Why does the melting curve of water have a negative slope? State the reduced Phase Rule equation for this system.
