Statement 1: For a system at equilibrium at constant and , .
Statement 2: At equilibrium the rates of the forward and reverse reactions are equal.
Options:
Answer:
B
Solution:
Statement 1 is true: the free energy is at its minimum, so no further change in is possible.
Statement 2 is true (dynamic equilibrium), but it is a kinetic statement.
The thermodynamic reason is that the Gibbs energies of products and reactants are balanced (, ), so Statement 2 does not explain Statement 1. Answer: (B).
