Chapter 10 - Reaction Rates and Chemical Equilibrium - 10.4 Using Equilibrium Constants - Questions and Problems - Page 386: 10.23

Answer

a. The equilibrium mixture contains mostly products. b. The equilibrium mixture contains mostly products. c. The equilibrium mixture contains mostly reactants.

Work Step by Step

If $K_c \approx 1$, there is an approximately equal quantity of reactants and products at equilibrium. If $K_c$ is a large number, like $3.7 \times 10^8$ and $1.1 \times 10^7$, there are mostly products at equilibrium. If $K_c$ is a small number, like $1.7 \times 10^{-56}$, there are mostly reactants at equilibrium.
