Chapter 15, Problem 61E

Consider the reaction:

   $\text{A}\left(\text{g}\right)\rightleftharpoons \text{B}\left(\text{g}\right)+\text{C}\left(\text{g}\right)$

Find the equilibrium concentrations of (A, B, and C for each value of K_c. Assume that the initial concentration of A in each case is 1.0 M and that the reaction mixture initially contains no products. Make any appropriate simplifying assumptions.

a. K_c= 1.0
b K_c= 0.010
c. $K_{\text{c}}=\text{1}.0\times {\text{l0}}^{\text{-5}}$
