For the electrochemical cell . $\mathrm{M}/{\mathrm{M}}^{+}//{\mathrm{X}}^{-}/\mathrm{X}, {\mathrm{E}}_{({\mathrm{M}}^{+}/\mathrm{M}=0.44\mathrm{V})}^0\text{ and }{\mathrm{E}}_{\left(\mathrm{x}/{\mathrm{x}}^{-}\right)}^0=0.33\mathrm{V}$ .From the data one can deduce that

$$\begin{gathered} \mathrm{SRP} \mathrm{of} \left({\mathrm{M}}^{\oplus }/\mathrm{M}\right)>\left(\mathrm{x}/{\mathrm{x}}^{\mathrm{\Theta }}\right) \\ \mathrm{So}, \left({\mathrm{X}}^{-}/\mathrm{X}\right)/-0.33//\left({\mathrm{M}}^{+}/\mathrm{M}\right)/0.44 \\ \begin{array}{l}{\mathrm{E}}_{\text{cell }}^0=0.44-0.33=0.11\mathrm{V}\\ {\mathrm{x}}^{\mathrm{\Theta }}+{\mathrm{M}}^{\oplus }\to \mathrm{x}+\mathrm{M}\text{ spontaneous. }\end{array} \\ \text{ But }{\mathrm{E}}^0\text{ for given cell }=-0.11\mathrm{V} \end{gathered}$$
