question

For the reaction 4C_2H_5Cl(g) + 13O_2(g) = 2 Cl_2 (g) + 8 CO_2 (g) + 10 H_2O (g) , \DeltaH_298°K = - 1229.6 kcal . Also, the heat of combustion per mole of C_2H_6 (g) to CO_2 (g) and H_2O (g) = - 341 kcal, the heat of formation per mole of H_2O (g) = - 57.8 kcal and the heat of formation per mole of HCl(g) = - 2.1 kcal. For the reaction C_2H_6 (g) + Cl_2 (g) = C_2H_5Cl(g) + HCl(g) (a) Calculate \DeltaH_298°K (b) Calculate \DeltaH_398°K for the first reaction assuming \DeltaC_P = - 10 cal/deg (c) Calculate \DeltaE_298°k for the first reaction
