I'd like you to check my calculations. The task is to calculate the time needed to produce 10 moles of hydrogen from water by electrolysis with a current of 1Amp.

I first wrote the equation of the reaction that occurs on the cathode

2H2O+2e- = H2 +2OH-

Then I derived the equation for time from Faraday's law

t=(F*n*z)/I

Since there are two electrons exchanging , z=2, I evaluated the equation and get

t= 1929.7 seconds which is .536 hours.

Is this correct ?

thanx
