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.Statement 1 For every chemical reaction at equilibrium, standard Gibbs energy of reaction is zero. Statement 2 At

Options

  1. AStatement 1 is true, Statement 2 is true, Statement 2 is a correct explanation for Statement 1.
  2. BStatement 1 is true, Statement 2 is true, Statement 2 is not a correct explanation for Statement 1.
  3. CStatement 1 is true, Statement 2 is false.
  4. DStatement 1 is false, Statement 2 is true

Correct answer

D. Statement 1 is false, Statement 2 is true

Step-by-step solution

At equilibrium, its free energy change, is zero and for a spontaneous process, ΔG<0\Delta G < 0 but at equilibrium standard free energy is not zero. Analysis of the ParagraphStatement 1 For every chemical reaction at equilibrium, standard Gibbs energy of reaction is zero. Statement 2 At
