Question
Calculate the A Hrxn for the reaction:
2H₂(g) + 2CO(g) → 2H₂O(g) + 2C(s)
Given that:
H₂O(g) + CO(g) → H₂(g) + CO₂(g)
A H₁ = -41.2 kJ
A H₂ = -206. KJ
3H₂(g) + CO(g) → H₂O(g) + CH4(g)
CO₂(g) + CH4(g) 2H₂O(g) + 2C(s)
A H3
= -15.5 kJ
Express your answer in decimal notation rounded to three significant figures.
