Question

For a spontaneous reaction the $\Delta G$, equilibrium constant (K) and $E{{}^0}_{cell}$ will be respectively :

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

Answer 1

Answer: (D)

$-ve,>1,+ve$

A spontaneous cell reaction has negative value of free energy change. For such reactions, the equilibrium constant is much larger than 1. The value of standard cell potential is positive for such reactions.
