From the enthalpies of reaction H_2 (g) + F_2 (g) rightarrow 2 HF (g) DElta H = -537 kJ C(s) + 2 F_2(g) rightarrow CF_4 (g) Delta H = -680 kJ 2 C (s) + 2 H_2 (g) rightarrow C_2 H_4 (g) Delta H = + 52.3 kJ Calculate Delta H for the reaction C_2 H_4(g) 6 F_2 rightarrow 2 CF_4 (g) + 4 HF (g) Combustion of acetone C_3H_6O(l) is given below C_3H_6O(l) + 4 O_2(g) rightarrow CO_2(g) + 3 H_2O(l) Delta H degree - -1790 kJ this information together with data from Table 5.3, to calculate the enthalpy of formation of acetone.
