Suppose a reaction takes place : 2 A ---> B with the standard heat of reaction equal to −40 kJ/mol. If 40 mols of B are produced, calculate the enthalpy change between the reactants and the products if both are at 25 oC. If both reactants and products are at the same temperature, must heat be added to or withdrawn from the reactor ?
