MCQ

Assertion : $\Delta H$ and $\Delta E$ are almost same for the reaction $N_2 (g) + O_2 (g) \rightleftharpoons 2NO(g)$
Reason : All reactants and products are gases.

A
If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
B
If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
✓
If the Assertion is correct but Reason is incorrect.
D
If both the Assertion and Reason are incorrect.

✓

Answer

Correct option: C.

If the Assertion is correct but Reason is incorrect.

c
$\Delta H = \Delta E + (RT)^{\Delta n}$ If there is no change in the moles of reactants (gaseous) and products (gaseous) $\Delta n = 0$

$\therefore $ $\Delta H = \Delta E$
