Chapter 17, Problem 71E

Consider the following reaction at 25.0°C:

$2{\text{NO}}_{\text{2}}\left(g\right)\rightleftharpoons {\text{N}}_{\text{2}}{\text{O}}_{\text{4}}\left(g\right)$

The values of ∆H° and ∆S° are −58.03 kJ/mol and −176.6 J/K · mol, respectively. Calculate the value of K at 25.0°C. Assuming ∆H° and ∆S° are temperature independent, estimate the value of K at 100.0°C.
