Thnx a tonne..i dont undrstnd this typ of prblmes...Okay, here goes:
CO2(g) + H2(g) -> CO(g) + H2O(g)
CO2 is being broken, so instead of -283, we take +283
H2O is being formed, so we use -286
BUT it is being formed in gaseous state, not liquid state, so we also take +44.
283 + 44 - 286 = +41.
So the answer is C.
