For The Reaction Cs Og Chemistry Question

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.
