A friend has reverted to childhood by wishing to make balloon bombs using
electrolysis of waster. I suggested that compression of the gasses would
"slow" the electrolysis due to the Le Chatelier principle.
My analysis is an additional electrical energy is necessary to do the integral
P dV.
No?, yes? off the beam?

p.s. Since my comment: his cell is a mason jar w/ a gas feed thru and
electrical feed thrus in the lid. Inflates a large "toy" balloon "nicely".
Very loud pop when he torches the balloon.

My guess would be no extra energy requirement: Faraday chose the ionic
transfer of elements as an absolute measure of current: the evolved gas
would simply take up a smaller volume.
