37. Following data is given for the reaction ${\mathrm{CaCO}}_{3}\left(\mathrm{s}\right)\to \mathrm{CaO}\left(\mathrm{s}\right)+{\mathrm{CO}}_{2}\left(\mathrm{g}\right)$

Predict the effect of temperature on the equilibrium constant of the above reaction.

Given that,
In the reaction,
Because $∆\mathrm{H}$ value is positive, so the reaction is endothermic. Hence, according to Le-Chateleir's principle, reaction will proceed in forward direction on increasing temperature. Thus, the value of equilibrium constant for the reaction increases.
