Question

Methyl tert-butyl ether (MTBE), C5H12O, a gasoline additive used to boost octane ratings, has ΔH∘f = -313.6kJ/mol.

Part A Write a balanced equation for its combustion reaction. Write a balanced equation for its combustion reaction. C5H12O(l)+6O2(g)→5CO2(g)+6H2O(l) C5H12O(l)+15/2O2(g)→5CO2(g)+6H2O(l) C5H12O(l)+15/2O2(g)→5H2CO3(g)+H2O(l) 2C5H12O(l)+5O2(g)→2C5H12O6(s) SubmitRequest Answer Part B Calculate its standard heat of combustion in kilojoules. Express your answer using four significant figures.

Answer 1

On rounding off to four significant figures the enthalpy of combustion is -3369kJ/mol
