Calculate the standard heat change of the reaction above, if the standard enthalpies of formation of CO2(g), H2O(g) and CO(g) and CO(g) in KJ mol -1 are - 394 -242 and - 110 respectively.
Answer Details
Standard heat change = Product - Reactant Product = -394 Reactant = CO + H2O = -242 + (-110) = -352 Heat change = -394 - (-352) = -42kj/mol Therefore the answer is D
