The heat of combustion of carbon to CO₂ is -393.5 kJ/mol. The heat released upon formation of 35.2 g of CO₂ from carbon and oxygen gas is
Options
(a) 315 kJ
(b) -630 kJ
(c) -3.15 kJ
(d) -315 kJ
Correct Answer:
315 kJ
Explanation:
Given: C + O₂ → CO₂, ΔH = – 393.5 kJ/mol. Amount of heat realeased on formation of 44 g CO₂ = 393.5 KJ. Amount of heat released on formation of 35.2 g CO₂ = 393.5 / 44 * 35.2 = 314.8 ≈ 315 kJ.
