Question
Measurements show that the energy of a mixture of gaseous reactants decreases by 374. 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 176. 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.
