Measurements show that the energy of a mixture of gaseous reactants decreases by 181.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 -86.kj of work is done on the mixture during the reaction.
Calculate the change in enthalpy of the gas mixture during the reaction. Round your answer to 2 significant digits.
