\(2{e^ - }\, + \,2{H_2}O\, \to \,{H_2}\, + \,2O{H^ - }\)

(valence factor) \(H_2=2\)

At \(NTP\) \(22400\,mL\) of \(H_2=1\,mole\) of \(H_2\,\,112\,mL\) of

\({H_2}\, = \,\frac{1}{{22400}}\, \times \,112\, = \,0.005\,mole\) of \(H_2\)

Moles of \(H_2\) produced

\( = \frac{{I\, \times t}}{{96500}}\, \times \) mole ratio

\(0.05 = \frac{{I\, \times 965}}{{96500}}\, \times \frac{{1\,\,mole\,\,of\,\,{H_2}}}{{2\,\,mole\,\,of\,\,{e^ - }}}\)

\(I\,=\,1.0\,A\)
