The surface of copper gets tarnished by the formation of copper oxide. $N _2$ gas was passed to prevent the oxide formation during heating of copper at $1250 K$. However, the $N _2$ gas contains $1$ mole $\%$ of water vapour as impurity. The water vapour oxidises copper as per the reaction given below:

$2 Cu ( s )+ H _2 O ( g ) \longrightarrow Cu _2 O ( s )+ H _2( g )$

$P _{ H _2}$ is the minimum partial pressure of $H _2$ (in bar) needed to prevent the oxidation at $1250 K$. The value of $\ln \left( p _{ H _2}\right)$ is. . . . .

(Given: total pressure $=1$ bar, $R$ (universal gas constant) $=8 JK ^{-1} mol ^{-1}, \ln (10)=2.3$. $Cu ( s )$ and $Cu _2 O ( s )$ are mutually immiscible.
