Question

If the cell reaction is spontaneous then:

• A. $\Delta G^o$ is +ve
• B. $E_{red}^o$ is -ve
• C. $E_{red}^o$ is +ve
• D. $\Delta G$ is -ve

Answer 1

Answer: (D)

$\Delta G$ is -ve

As we know,
For a spontaneous cell reaction $E_{cell}^o>0$
and accoding to $\Delta G^o=-nF{E}^o=-ve$ and
$Q<K_c$ so reaction moves forward to attain eqm.
