Question

For a particular isomer of C, H,,, the combustion reaction produces 5104.1 kJ of heat per mole of C, H, (g) consumed, unde st

Answer 1

Answer #1

Given:

ΔHo rxn = -5104.1 KJ/mol

Hof(O2(g)) = 0.0 KJ/mol

Hof(CO2(g)) = -393.509 KJ/mol

Hof(H2O(g)) = -241.818 KJ/mol

Balanced chemical equation is:

C8H18(g) + 25/2 O2(g) ---> 8 CO2(g) + 9 H2O(g)

ΔHo rxn = 8*Hof(CO2(g)) + 9*Hof(H2O(g)) - 1*Hof( C8H18(g)) - 25/2*Hof(O2(g))

-5104.1 = 8*(-393.509) + 9*(-241.818) - 1*Hof(C8H18(g)) - 25/2*(0.0)

Hof(C8H18(g)) = -220.334 KJ/mol

Answer: -220.3 KJ/mol
