Question

The standard enthalpies of formation of CH4 (gas), CO2 (gas) and H2O (liquid) are – 75, – 394 and – 285 kJ/mol respectively. The standard enthalpy of the reaction, CH4 (g) + 2 O2 (g) --> CO2 (g) + 2 H2O (l) is​

Answer 1

Explanation:

Ideal Gas Enthalpy of Oxygen (O2) Enthalpy of Formation: 0 (kJ/kmol) Molecular Weight: 32 (kg/kmol)

Temp. [K] Enthalpy [kJ/kmol] Enthalpy [kJ/kmol]

298 0

300 54 10862

310 348 11188

320 643 11515
