Answer to Question #268482 in General Chemistry for DDD

Question

2. Hydrogen gas, H2, reacts explosively with gaseous chlorine, Cl2, to form hydrogen chloride, HCl (g). What is the enthalpy change for the reaction of 1 mole of H2 (g) with 1 mole of Cl2 (g) if both the reactants and products are at standard state conditions? The standard enthalpy of formation of HCl (g) is

-92.3 kJ/mol.
