JEE Advanced · Chemistry · 6. Thermodynamics (C)
Statement 1 For every chemical reaction at equilibrium, standard Gibbs energy of reaction is zero.
Statement 2 At constant temperature and pressure, chemical reactions are spontaneous in the direction of decreasing Gibbs energy.
- A Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
- B Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
- C Statement 1 is true, Statement 2 is false.
- D Statement 1 is false, Statement 2 is true
Answer & Solution
Correct Answer
(D) Statement 1 is false, Statement 2 is true
Step-by-step Solution
Detailed explanation
At equilibrium, its free energy change, is zero and for a spontaneous process, \(\Delta G < 0\) but at equilibrium standard free energy is not zero.
