MCQ
For which of the reaction $\Delta H = \Delta E$
- A${N_2} + 3{H_2}$ $ \rightleftharpoons $ $2N{H_3}$
- ✓${N_2} + {O_2} \to 2NO$
- C$2Na + C{l_2} \to 2NaCl$
- D$PC{l_5} \to PC{l_3} + C{l_2}$
✓
Answer
Correct option: B.
${N_2} + {O_2} \to 2NO$
(b)${N_2}(g) + {O_2}(g) \to 2NO(g)$; $\Delta {n_g} = 2 - 2 = 0$
$\Delta H = \Delta E + \Delta {n_g}RT$; $\Delta H = \Delta E + 0$; $\Delta H = \Delta E$
$\Delta H = \Delta E + \Delta {n_g}RT$; $\Delta H = \Delta E + 0$; $\Delta H = \Delta E$
