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.
  1. Statement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
  2. Statement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
  3. Statement 1 is true, Statement 2 is false.
  4. Statement 1 is false, Statement 2 is true

Solution

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. Analysis of the Paragraph
