question 22 of 25
what information does gibbs free energy give about a reaction?
a. it tells how quickly the reaction will proceed to equilibrium.
b. it tells if the reaction will proceed spontaneously or not.
c. it tells what the activation energy of the forward reaction is.
d. it tells what the most stable forms of the products are.

Explanation:

Gibbs free - energy ($\Delta G$) is used to predict the spontaneity of a reaction. If $\Delta G<0$, the reaction is spontaneous; if $\Delta G = 0$, the reaction is at equilibrium; if $\Delta G>0$, the reaction is non - spontaneous. It does not provide information about reaction rate (how quickly it proceeds to equilibrium), activation energy, or the most stable forms of products.

Answer:

B. It tells if the reaction will proceed spontaneously or not.
