The enthalpy change for the forward reaction is -92kJ/mol. State and explain how the value of Kp would change if the temperature was increased.

The value of Kp would decrease.Using Le Chatelier's principle the position of equilibrium would shift so as to oppose the change.The endothermic (backward) reaction would therefore be favoured in order to...
