3. Express the dependence of the thermal effect of the reaction or temperature, if the standard enthalpy of formation of the substances participating in the reaction and the equation for the dependence Cp = f (T) are known.
2. Calculate the thermal effect of the reaction at temperature T and determine how different QP is from QV at this temperature (the thermal effect of the reaction at constant pressure from the thermal effect at constant volume).
Chemical reactions are presented in table. 3.

option Reaction Temperature, K
3 NH4Cl(s) =NH3 HCl 500
