Chapter 14, Problem 96RQ

At $\text{2000 °C}$, the decomposition of ${\text{CO}}_{\text{2}}$,

${\text{2CO}}_{\text{2}}\left(g\right)\stackrel{}{\rightleftharpoons }\text{2CO}\left(g\right){\text{ + O}}_{\text{2}}\left(g\right)$

has $K_{\text{c}}\text{= 6}{\text{.4 × 10}}^{\text{-7}}\text{.}$

If a 1.00 L container holding $\text{1}{\text{.00 × 10}}^{\text{-2}}$ mol of ${\text{CO}}_{\text{2}}$ is heated to $\text{2000 °C}$, how much heat, in joules, is absorbed or evolved when the system reaches equilibrium?
