alleryStart learning →For which reaction is ΔH equal to ΔU?
APCl5(g) → PCl3(g) + Cl2(g)
BN2(g) + 3H2(g) → 2NH3(g)
CH2(g) + Cl2(g) → 2HCl(g)
D2SO2(g) + O2(g) → 2SO3(g)
Answer & Solution
Correct answer: C. H2(g) + Cl2(g) → 2HCl(g)
Two moles of gas appear on each side of the HCl reaction, so Δng = 0 and ΔH = ΔU.
