Question: One method for preparing hydrogen as a fuel from methanol uses a two-step process with the overall reaction CH 3 OH(l) + H 2 O(l)

One method for preparing hydrogen as a fuel from methanol uses a two-step process with the overall reaction CH₃OH(l) + H₂O(l) → 3 H₂(g) + CO₂(g).

(a) What is the standard reaction enthalpy of this process?

(b) What is the standard enthalpy of combustion of the hydrogen produced?

(d) Which process generates more heat at constant pressure, the direct combustion of methanol in part (c) or the two-step process (parts (a) and (b) combined)?
