Delta G of galvanic cells

Postby Katherine Grillo 1B » Fri Mar 15, 2019 9:21 pm

Why do we know that the delta G of galvanic cells will always be less than 0?

A galvanic cell by definition is an electrochemical cell in which a spontaneous chemical reaction is used to generate an electric current. Since the chemical reaction in a galvanic cell is always spontaneous, delta G will always be negative for a galvanic cell.

Because it's a spontaneous reaction that converts electrical energy to chemical energy.
