1. The following enthalpy changes are known for reactions at 25 "C and one atm. No Reaction AH (kJ/mol) CsHolg) + Hz{g) CHs(g) -123.8 2 CHa(g) + 502(8)→ 3CO; (8) + 4H20(1) -2220.0 3. Ha(8) + % Oz(8)→캐20(1) -285.8 H20(1) → H,0(g) 43.9 5. C(diamond) + O(g) → CO2(g) -395.4 C(graphite) + 02(8) → CO2(8) 393.5 Using Hess' Law, calculate the heat of formation of propylene from the above reactions. 1.
