The standard free energy change for the reaction: \[{{H}_{2}}\left( g \right)+2AgC{{l}_{(s)}}\xrightarrow{{}}2A{{g}_{\left( s \right)}}+2{{H}^{+}}_{\left( aq \right)}+2C{{l}^{-}}_{(aq)}\] is \[-10.26\] kcal \[mo{{l}^{-1}}\] at\[25{}^\circ C\]. A cell using above reaction is operated at \[25{}^\circ C\] under \[{{P}_{{{H}_{2}}}}=1\] atm, \[[{{H}^{+}}]\] and \[\left[ C{{l}^{-}} \right]=0.1.\] Calculate e.m.f. of cell.

Answer:

0.34
