For the reaction C(s) + O₂(g)
Options
(a) ΔH = ΔE
(b) ΔH < ΔE
(c) ΔH > ΔE
(d) either ΔH > ΔE or ΔH < ΔE
Correct Answer:
ΔH = ΔE
Explanation:
In the reaction C(s) + O₂(g) → CO₂(g), there is no change in the number of moles of gaseous components (Δn = 1 – 1 = 0).
As ΔH = ΔE + ΔnRT. Thus in this case ΔH = ΔE.
