Question

The quantity which is not zero for an element in its standard state at $298K$ is

• A. $S$${}^0$
• B. $H$${}^0$
• C. $G$${}^0$
• D. Both $H$${}^0$ and $S$${}^0$

Answer 1

The correct option is A $S$${}^0$

$H^{\circ }$ and $G^{\circ }$are zero for an element at its standard state
$S^{\circ }$is not zero for an element at its standard state
