Solution

The correct option is C $H_{2} (g) + I_{2} (g) ⟶ 2 H I (g)$
Solution:- (C) ${H_{2}}_{(g)} + {I_{2}}_{(g)} ⟶ 2 {H I}_{(g)}$
$Δ H = Δ E + Δ n_{g} R T$
Hence $Δ H = Δ E$ for $Δ n_{g} = 0$
Hence for the reaction,
${H_{2}}_{(g)} + {I_{2}}_{(g)} ⟶ 2 {H I}_{(g)}$
$Δ n_{g} = n_{P} - n_{R} = 2 - (1 + 1) = 0$
$∴ Δ H = Δ E$
