Galvanic Cells 14.3

Postby donnanguyen1d » Sun Feb 18, 2018 1:52 pm

The textbook says the current produced can be used to electrical work but it also says although energy is released as heat, there is no electrical work done. So which is it? or what do we need to understand about electrical work conceptually in the galvanic cell context?

Maybe it's because the voltage created by concentration cells can light a bulb, hence the electrical work?

If the reaction takes place in a cell that performs electrical work, then the heat released is diminished by the amount of electrical work done.
