Product description
- Determine the enthalpy of the reaction 2C (t) 2H2 (g) \u003d C2H4 (g), knowing the enthalpies of the following reactions:
C2H4 (g) H2 (g) = C2H6 (g) ∆H° = –137 kJ/mol
C2H6 (g) 7/2O2 (g)= 2CO2 (g) 3H2O (l) ∆H° = –1560 kJ/mol
C O2 (g) = CO2 (g) ∆H° = –393.5 kJ/mol
H2 (g) 1/2O2 (g) = H2O(l) ∆H° = –285.8 kJ/mol
