229263 For a given exothermic reaction, $K_{p}$ and $K_{p}^{\prime}$ are the equilibrium constants at temperature $T_{1}$ and $T_{2}$ respectively. Assuming that heat of reactions is constant if temperature range between $T_{1}$ and $T_{2}$ it is readily observed that

1 $\mathrm{K}_{\mathrm{p}}>\mathrm{K}_{\mathrm{p}}^{\prime}$
2 $\mathrm{K}_{\mathrm{p}}<\mathrm{K}_{\mathrm{p}}^{\prime}$
