This I gave it for prof.kankan and he did not do it can any one do it instead look at chemistry homework I posted and see if you can help me with that tonight.
Ethene is converted to ethane by the reaction C2H4(g) + H2(g) → C2H6(g) C2H4 flows into a catalytic reactor at 25.0 atm and 300.°C with a flow rate of 1367 L/min. Hydrogen at 25.0 atm and 300.°C flows into the reactor at a flow rate of 1500. L/min. If 11.0 kg of C2H6 are collected […]
5. What is the molar enthalpy of the formation of 1mol H2SO4(l) given the following information? 2H2(g) + O2(g) → 2H2O(g) ΔHrxn = -484kJ 2S(s) + 3O2(g) → 2SO3(g) ΔHrxn = -890kJ H2(g) + 2O2(g) + S(s)→ H2SO4(l) ΔHrxn = -814kJ H2O(g) + SO3(g)→ H2SO4(l) ΔHrxn = xkJ
