Question

Write the formation equation for CH_{4} from the standard states of its elements and give its standard enthalpy of formation

Accepted Answer

C (s) + 2 H_{2} (g) → CH_{4} (g) ΔH°_{f} = -74,850 kJ/mol

Answer

C (g) + 2 H_{2} (g) → CH_{4} (g) ΔH°_{f} = -74,850 kJ/mol

Answer

C (s) + H_{2} (g) → CH_{4} (s) ΔH°_{f} = -74,850 kJ/mo

Answer

C (s) + 4 H (g) → CH_{4} (g) ΔH°_{f} = -74,850 kJ/mol
