Chapter 15.4, Problem 1CP

Use the following information to answer questions 15.4.1 and 15.4.2: $K_c$ for the reaction:

$\text{A + B}\underset{}{\rightleftarrows }\text{ 2C}$

$\text{is 1}\text{.7 }\times {\text{ 10}}^{\text{-2}}\text{ at 250°C}\text{.}$

What will the equilibrium concentrations of A, B, and C be at this temperature if ${\left[\text{A}\right]}_{\text{i}}\text{=}{\left[\text{B}\right]}_{\text{i}}\text{=0}\text{.750 }M\left({\left[\text{C}\right]}_{\text{i}}\text{=0}\right)\text{?}$

$\begin{array}{l}a)\hfill \\ 6.1\times {10}^{-3}M,6.1\times {10}^{-3}M,0.092M\hfill \\ b)\hfill \\ 0.046M,0.046M,0.092M\hfill \\ c)\hfill \\ 0.70M,0.70M\mathrm{.0.046}M\hfill \\ d)\hfill \\ \begin{array}{l}0.70M,0.70M,0.092M\\ e)0.087M,0.087M,0.66M\end{array}\hfill \end{array}$
