Which of the following statements is/are correct? A large negative free-energy change for a reaction means that ________
I. the equilibrium constant for the reaction is large.
II. the equilibrium constant for the reaction is small.
III. the reaction greatly favors formation of the products.
IV. only a small amount of product is produced at equilibrium.

Question

Quizplus · Accepted Answer

A large negative free-energy change for a reaction indicates that the reaction greatly favors the formation of products, which is statement III. This also means that the equilibrium constant for the reaction is large, which is statement I. Therefore, both statements I and III are correct. Statement II is incorrect because a large negative free-energy change corresponds to a large equilibrium constant, not a small one. Statement IV is also incorrect since a large negative free-energy change suggests that a significant amount of product is produced at equilibrium, not a small amount.
