O THERMOCHEMISTRY Understanding the definition of enthalpy Measurements show that the energy of a mixture of gaseous reactants decreases by 302. 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-93. kJ of work is done on the mixture during the reaction Calculate the change in enthalpy of the gas mixture during the reaction. Be sure your answer has the correct number of significant digits. kJ 27 O exothermic Is the reaction exothermic or endothermic? O endothermic
