MCQ
The heat of formation of ${H_2}O(l)$ is $-68.0\, kcal$, the heat of formation of ${H_2}O(g)$ is likely to be........$kcal$
- A$-68$
- ✓$-67.4$
- C$80$
- D$-58.3$
✓
Answer
Correct option: B.
$-67.4$
(b)When ${H_2}{O_{(l)}}$ is convert to form ${H_2}{O_{(g)}}$, heat is absorbed hence $\Delta {H_1} > \Delta {H_2}$.
