Consider the following reaction at 248 C and 1.00 atm: CH3Cl (g) + H2(g) --> CH4(g) + HCl (g)For this reaction, the enthalpy change at 248 C is -83.3 kJ/mol. At constant pressure the molar heat capacities (Cp) for the compounds are as follows: CH3Cl (48.5 J/mol K) ; H2 (28.9 J/mol K) ; CH4 (41.3 J/mol K) ; HCl (29.1 J/mol K) Assuming that the Cp values are independent of temperature, calculate ∆H for this reaction at 25 C.
