Question

Write the formation equation for CH₄ from the standard states of its elements and give its standard enthalpy of formation

Accepted Answer

C (s) + 2 H₂ (g) → CH₄ (g) ΔH°_f = -74,850 kJ/mol

Answer

C (g) + 2 H₂ (g) → CH₄ (g) ΔH°_f = -74,850 kJ/mol

Answer

C (s) + H₂ (g) → CH₄ (s) ΔH°_f = -74,850 kJ/mo

Answer

C (s) + 4 H (g) → CH₄ (g) ΔH°_f = -74,850 kJ/mol
