Measurements show that the enthalpy of a mixture of gaseous reactants decreases by 365. 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 102. kJ of work is done on the mixture during the reaction. Calculate the change in energy of the gas mixture during the reaction. Be sure your answer has the correct number of significant digits. Is the reaction exothermic or endothermic? O exothermic O endothermic

Question
Measurements show that the enthalpy of a mixture of gaseous reactants decreases by 365. 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
102, kJ of work is done on the mixture during the reaction.
Calculate the change in energy of the gas mixture
during the reaction. Be sure your answer has the
correct number of significant digits.
O exothermic
Is the reaction exothermic or endothermic?
O endothermic
