$($a$)$ Write the cell reactions and predict whether it is spontaneous or non$-$spontaneous in a cell at $298K$ and also calculate the equilibrium constant of the cell reaction

$Zn,Z{n}^{2+}\frac{IM}{\frac{?}{?}}I(IM),$CuI,$Cu$

$E(Z\frac{n^{2+}}{Z}n)=-0\mathrm{.}76V$

$E(CuI,I^{-},Cu)=-0\mathrm{.}17V$
