Δ H =Δ E +Δ nRT Δ n= change in number of moles of products and reactant species. N 2( g )+ O 2( g ) leftharpoons 2 NO ( g ) Δ n=2-2=0 Δ H =Δ E + O × RT or, Δ H =Δ E.

Q. Assertion : $Δ H$ and $Δ E$ are almost the same for the reaction, $N_{2 (g)} + O_{2 (g)} ⇌ 2 N O_{(g)}$
Reason : All reactants and products are gases.

If both assertion and reason are true and the reason is the correct explanation of the assertion

If both assertion and reason are true and the reason is not the correct explanation of the assertion

If assertion is true but reason is false

If both assertion and reason are false

$Δ H = Δ E + Δ n RT$

$Δ n =$ change in number of moles of products and reactant species.

$N_{2 (g)} + O_{2 (g)} ⇌ 2 N O_{(g)}$

$Δ n = 2 - 2 = 0$

$Δ H = Δ E + O \times RT$ or, $Δ H = Δ E$ .

Q. Assertion : ΔH and ΔE are almost the same for the reaction, N2(g)​+O2(g)​⇌2NO(g)​ Reason : All reactants and products are gases.
