Two processes that can be used to generate hydrogen are the electrolysis of water 2 H 2

Question:

Two processes that can be used to generate hydrogen are the electrolysis of water 2 H₂O(ℓ) → 2 H₂(g) + O₂(g) and the reaction of methane with steam CH₄(g) + H₂O(g) → 3 H₂(g) + CO(g)
(a) Calculate Δ_rG° for each reaction.
(b) For each reaction, calculate ΔG° per mole of hydrogen produced.
(c) Which process do you think is better to use to obtain hydrogen? Explain.
