For the following concentration cell, to be  spontaneous Pt $\left({\mathrm{H}}_2\right){\mathrm{P}}_1\text{ atm. }\left|\mathrm{HCl}\right|\mathrm{Pt}\left({\mathrm{H}}_2\right){\mathrm{P}}_2$  Which of the following is correct?

The Nernst equation is 

${\mathrm{E}}_{\mathrm{cell}}={\mathrm{E}}_{\mathrm{cell}}^{\mathrm{o}}+\hspace{0.17em}\frac{0.0591}{2}\log \frac{{\mathrm{P}}_1}{{\mathrm{P}}_2}$

For the cell reaction to be spontaneous, ${\mathrm{E}}_{\mathrm{cell}}^{ }>\hspace{0.17em}+\mathrm{ve}$, which is possible  if P₁> P₂.
