Hydrogen is a gas used as a fuel in different types of fuel cells, such as phosphoric acid, solid oxide and proton-exchange membrane fuel cells. This fuel can be obtained from natural gas through the following reactions: Steam-Methane Reforming: CH,(g) + H20(g) → CO(g) + 3H2(g) AĤ¤ = 206.16 kJ/mol Water-Gas Shift Reaction: CO2(g) + H2(g) → CO(g) + H20(g) AĤÇ = 41.15 kJ/mol (i) Determine the enthalpy of the following reaction by applying Hess's Law: 2CH,(g) + 3H20(g) → CO(g) + CO2(g) + 7H2(g) (ii) Verify the value obtained in Q1.(i) via the standard heat of formation.

Question
Transcribed Image Text:Hydrogen is a gas used as a fuel in different types of fuel cells, such as phosphoric acid,
solid oxide and proton-exchange membrane fuel cells. This fuel can be obtained from
natural gas through the following reactions:
Steam-Methane Reforming:
CH,(g) + H20(g) → CO(g) + 3H2(g)
AĤ¤ = 206.16 kJ/mol
Water-Gas Shift Reaction:
CO2(g) + H2(g) → CO(g) + H20(g)
AĤÇ = 41.15 kJ/mol
(i)
Determine the enthalpy of the following reaction by applying Hess's Law:
2CH,(g) + 3H20(g) → CO(g) + CO2(g) + 7H2(g)
(ii)
Verify the value obtained in Q1.(i) via the standard heat of formation.
