Question

For a spontaneous reaction $\Delta G$, equilibrium $K$ and $E_{cell}$ will be respectively:

• A. $-ve,>1,+ve$
• B. $+ve,>1,-ve$
• C. $-ve,<1,-ve$
• D. $-ve,>1,-ve$

Answer 1

The correct option is A $-ve,>1,+ve$

For a spontaneous reaction, we have

$\Delta G=-ve$ and we have

$\Delta G=-RTlnK$

so, $lnK=+ve$
