Question

For a particular isomer of C 8 H 18 , the combustion reaction produces 5099.5 kJ of heat per mole of C 8 H 18 ( g ) consumed, under standard conditions. C 8 H 18 ( g ) + 25 2 O 2 ( g ) ⟶ 8 CO 2 ( g ) + 9 H 2 O ( g ) Δ H ∘ rxn = − 5099.5 kJ / mol What is the standard enthalpy of formation of this isomer of C 8 H 18 ( g ) ? Standard enthalpy of formation values can be found in this table of thermodynamic values.   show all work
