Question
Measurements show that the energy of a mixture of gaseous reactants decreases by 305. 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 -151. 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 3
significant digits.
