O THERMOCHEMISTRY Understanding the definition of enthalpy Measurements show that the energy of a mixture of gaseous reactants decreases by 322. kJ during a certain chemical reaction, whi constant pressure. Furthermore, by carefully monitoring the volume change it is determined that 99. kJ of work is done on the mixt Calculate the change in enthalpy 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
