Question

Calculate the enthalpy of formation of propane c3h8 if it's enthalpy of combustion is -2280kj mol-1 .given enthalpy of formation of co2 and h2o are -393.5 & -286.1 kj Mol respectively​

Answer 1

Answer:

The standard enthalpy of formation of carbon monoxide is -99 kJ/mol. C(s) +½O₂(g) → CO(g); ΔH=? To solve this problem, we use Hess's Law. Our target equation has CO(g) on the right hand side, so we reverse equation 2 and divide by 2.
