Question

For the system $S\left(s\right)+O_2\left(g\right)\to S{O}_2\left(g\right)$ relation between $\Delta H$ and $\Delta E$ is______

• A. $\Delta$H > $\Delta$E
• B. $\Delta$E > $\Delta$H
• C. $\Delta$H = 0
• D. $\Delta$H = $\Delta$E

Answer 1

The correct option is D $\Delta$H = $\Delta$E

$\Delta H=\Delta E+\Delta n_{g}RT$
For the system
$S\left(s\right)+O_2\left(g\right)\to S{O}_2\left(g\right)$
$\Delta n_g=0$
$\therefore \Delta H=\Delta E$

Option D is correct.
