Measurements show that the enthalpy of a mixture of gaseous reactants increases by 238. kJ during a certain chemical reaction, which is carried out at a constant pressure. Furthermore, by carefully monitoring the volume change it is determined that 197. kJ of work is done on the mixture during the reaction 1. Calculate the change in energy of the gas mixture during the reaction. Round your answer to 3 significant digits.2. Is the reaction exothermic or endothermic?
