49. Solution to Chemistry Problem

2. Express the dependence of the heat of reaction on temperature if the standard enthalpies of formation of the substances participating in the reaction and the equations of the dependence Cp=f(T) are known.
2. Calculate the heat of reaction at temperature T and determine how much QP differs from QV at this temperature (the heat of reaction at constant pressure from the heat of reaction at constant volume).
Chemical reactions are presented in Table 3.
