MCQ
$Co|Co^{2+}(C_2)||Co^{2+}(C_1)|Co$, for this cell, $\Delta G$ is negative if
- A$C_2 > C_1$
- ✓$C_2 < C_1$
- C$C_1 = C_2$
- Dunpredictable
For concentration cell $\mathrm{E}_{\text {cell }}^{o}=0$
$\mathrm{E}_{\text {cell }}=-\frac{0.059}{\mathrm{n}} \log \frac{\mathrm{C}_{2}}{\mathrm{C}_{1}}$
$\Delta G=$ negative ie $E_{\text {cell }}=$ positive For $E_{\text {cell }}$ positive $=C_{1}>C_{2}$

True statement about sequence on the basis of assumption that $R$ contains $3$ different groups is
$\mathop R\limits^{\delta \oplus } \,\mathop {Br}\limits^{\delta \,\Theta } \, \rightleftharpoons $ $\mathop {\boxed{{R^ \oplus }B{r^\Theta }}}\limits_{(a)} \,\,\, \rightleftharpoons \,$$\,\mathop {\boxed{{R^ \oplus }}\,\boxed{B{r^\Theta }}\,}\limits_{(b)} \,\, \rightleftharpoons $ ${\boxed{{R^ \oplus }}}$ $ \rightleftharpoons $ $\mathop {\,\boxed{B{r^\Theta }}\,}\limits_{(c)} \,$
$4M + 8CN^-+ 2H_2O + O_2 \rightarrow 4[M(CN)_2]^-+ 4OH^-$
$2[M(CN)_2]^-+ Zn \rightarrow [Zn(CN)_4]^{2-} + 2M$
