Question

How much heat is produced if 22.2 g of octane (C₈H₁₈) is combusted according to the following reaction?

2 C₈H₁₈ (g) + 25 O₂ (g) --> 16 CO₂ (g) + 18 H₂O (l) ΔH = -5471 kJ/mol

Answer 1

Answer #1

Number of moles of C8H18 in 22.2 g = amount of C8H18 (g)/mw of C8H18 (g/mole)= 22.2 g/114.23g/mole= 0.1943 moles

According to the given balanced equation

Combustion of 1 mole of C8H18 produces 5471 kJ heat

Therefore combustion of 0.1677 mole of C8H18 will produce=0.1943 X 5471 kJ heat= 1063.02 kJ of heat
