Oxidation of water equation
WebThe symbol equation for this reaction is: CH₄ (g) + O₂ (g) → CO₂ (g) + H₂O (l) Can you work out the word equation for this reaction? Show answer The word equations is: Methane + … Both the oxidation and reduction steps are pH dependent. Figure 1 shows the standard potentials at pH 0 (strongly acidic) as referenced to the normal hydrogen electrode (NHE). 2 half reactions (at pH = 0) Oxidation 2H2O → 4H + 4e + O2 E° = 1.23 V vs. NHE Reduction 4H + 4e → 2H2 E° = 0.00 V vs. NHE Overall 2H2O → 2H2 + O2 E°cell = -1.23 V; ΔG = 475 kJ/mol
