We use hess's law to calculate enthalpy changes that cannot be measured. one such reaction is the conversion of methane to ethylene: 2 ch4(g) → c2h4(g) + 2 h2(g) calculate δhrxn for this reaction using the thermochemical data: ch4(g) + 2 o2(g) → co2(g) + 2 h2o(g) δh = -802.5 kj c2h4(g) + h2(g) → c2h6(g) δh = -136.4 kj 2 h2(g) + o2(g) → 2 h2o(g) δh = -483.6 kj 2 c2h6(g) + 7 o2(g) → 4 co2(g) + 6 h2o(g) δh = -2856.8 kj
