C8H18(g)+252O2(g)⟶8CO2(g)+9H2O(g) ΔH∘rxn=−5093.7 kJ/mol

What is the standard enthalpy of formation of this isomer of C8H18(g)?

Expert Solution

I have taken the standard enthalpy of formation values from standard text books (as they are required to solve this question)

For

CO2 = -393.5 kJ/mol

H2O (g) = -241.8

O2 = 0
