Measurements show that the enthalpy of a mixture of gaseous reactants increases by 215. 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 -155. kJ of work is done on the mixture during the reaction.
Calculate the change in energy of the gas mixture during the reaction. Round your answer to 2 significant digits.
Is the reaction exothermic or endothermic?
