Question 1

Using the following thermochemical equation, determine the amount of heat produced per kg of CO2 formed during the combustion of benzene (C6H6).

2C6H6(l) + 15O2(g) → 12CO2(g) + 6H2O(g)DrH° = -6278 kJ

◦ 8.40 × 105 kJ (kg CO2)-1
◦ 4.34 × 104 kJ (kg CO2)-1
◦ 1.43 × 105 kJ (kg CO2)-1
◦ 2.30 × 104 kJ (kg CO2)-1
◦ 1.19 × 104 kJ (kg CO2)-1

Question 2

Using the following thermochemical equation, determine the amount of heat produced from the combustion of 24.3 g benzene (C6H6). The molar mass of benzene is 78.11 g mol-1

2C6H6(l) + 15O2(g) → 12CO2(g) + 6H2O(g)DrH° = -6278 kJ

◦ 40.1 kJ C6H6
◦ 3910 kJ C6H6
◦ 977 kJ C6H6
◦ 1950 kJ C6H6
◦ 0.302 kJ C6H6
