76. Solving a chemistry problem

9. Express the dependence of the thermal effect of the reaction or temperature, if the standard enthalpies of formation of the substances involved in the reaction are known, and the equation of the dependence Cp \u003d f (T).
2. Calculate the thermal effect of the reaction at temperature T and determine how much QP differs 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.
