In which of the following E = H - Vidyadip

MCQ

In which of the following $\Delta E = \Delta H$

A
${N_2}{O_4}(g)$ $ \rightleftharpoons $ $2N{O_2}(g)$
B
$2S{O_2}(g) + {O_2}(g)$ $ \rightleftharpoons $ $2S{O_3}(g)$
✓
${H_2}(g) + {I_2}(g)$ $ \rightleftharpoons $ $2HI(g)$
D
${H_2}(g) + \frac{1}{2}{O_2}(g)$ $ \rightleftharpoons $ ${H_2}O(l)$

✓

Answer

Correct option: C.

${H_2}(g) + {I_2}(g)$ $ \rightleftharpoons $ $2HI(g)$

(c)Here $\Delta n = 0$ so, $\Delta E = \Delta H$.
