In the following gas phase reaction, Kc is much less than 1. At equilibrium, which of the following statements is true?

Question

Quizplus · Accepted Answer

A value of Kc much less than 1 indicates that the reaction strongly favors the reactants, so at equilibrium, the concentration of reactants is much greater than the concentration of products. A catalyst will not change the position of equilibrium, so statement B is incorrect. Statement A is incorrect because it is the opposite of what is expected with a Kc much less than 1. Statement D is incorrect because the concentrations of products and reactants cannot be approximately equal if Kc is much less than 1.
