Problem Details

Methyl tert-butyl ether (MTBE, C 5H12O, a gasoline additive used to boost octane ratings, has ΔH°= -313.6 kJ/mol. 

Part A

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) → 2C 5H12O6 (s)

Part B 

Calculate its standard heat of combustion in kilojoules.

Express your answer using four significant figures
