Which of the following statements is/are correct? A large equilibrium constant means that ________
I.the standard free-energy change for the reaction is large and negative.
II. the standard free-energy change for the reaction is large and positive.
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 equilibrium constant (K) indicates that the reaction greatly favors the products (III), meaning that more products are present at equilibrium than reactants. This is because the numerical value of K is equal to the ratio of the concentrations of products and reactants at equilibrium. A large K can also be calculated if the standard free-energy change for the reaction (ΔG°) is large and negative (I), which means that the reaction is thermodynamically favorable.
