question

Calculate the heat of formation of CH_4(g) in the reaction: C(graphite) + 2H_2(g) = CH_4(g) , using the reactions below and their given \DeltaH° values CH_4(g) + 2O_2(g) = CO_2(g) + 2H_2O(1) \DeltaH° = -212.80 kcal mole^-1 C(graphite) + C_2 (g) = CO_2 (g)\DeltaH° = -94.05 kcal mole^-1 H_2(g) + (1/2) O_2(g) = H_2O(1)\DeltaH° = -68.32 kcal mole^-1
