--------------------------------------------------------------------------------------
Overall:
Standard cell potential,
So,
We know, standard free energy change at ():
where, n is number of electron exchanged during cell reaction, 1F equal to 96500 C/mol
Here n = 2
So,
The answer is Steam because gas has the most motion
