Answer 1

13. Enzymes can help the reaction to go in either direction by altering the gibbs free energy state of activation but they do not alter the gibbs free energy of the reaction and also cannot alter the equilibrium of the reaction. The enzymes are highly specific for its substrate. Hence the correct answer is: are specific.

14. A reaction can occur spontaneously when the Gibbs free energy of the reaction is negative. Hence the correct answer is: a negative value.
