The dependence of the equilibrium constant of a retain on temperature is given by the van't Hoff equation:
\(lnK = \frac{-\Delta H^{0}}{RT}+C\)
where C is a constant.The following table gives the equilibrium constant (Kp) at various temperatures for the reaction of nitrogen monoxide with oxygen gas that produces nitrogen dioxide:
T(K) Kp
600 138
700 5.12
800 0.436
900 0.0626
1000 0.0130
Caculate the enthalpy of the reaction.
