$2NOB{r_{(g)\,}}\, \rightleftharpoons \,2N{O_{(g)}}\, + \,B{r_{2(g)}}$
if ${P_{B{r_2}}}$ is $\frac {P}{4}$ At equilibrium and $P$ is total pressure then calculate $\frac {P}{K_P}.$
$Zn^{2 + }(aq.) + 2e⇔ Zn(s)$; $→$ $ -0.762$
$Cr^{3 + }(aq) + 3e ⇔ Cr(s)$; $→$ $-0.740$
$2H^ +(aq) + 2e⇔ {H_2}(g)$; $→$ $0.00$
$Fe^{3+}(aq) + e ⇔ Fe^{2+}(aq)$; $→$ $0.770$
