For the cell, ${\mathrm{Zn}}_{(\mathrm{s})}+\underset{(\mathrm{aq})}{{\mathrm{Cu}}^{+2}}\rightleftharpoons \underset{(\mathrm{aq})}{{\mathrm{Zn}}^{+2}}+{\mathrm{Cu}}_{(\mathrm{s})}$ the entropy change $\left(\Delta {\mathrm{S}}^0\right)$ is $96.5{\mathrm{JK}}^{-1}{\mathrm{mol}}^{-1}$ then temperature coefficient for the emf of the cell is $\left(x\times 10^{-y}\right)$ then $\left(\frac{x}{y}\right)$ value is
