Galvanic Cell emf
What’s happening in the Galvanic Cell when emf is negative and the cell is absorbing energy (Delta G >0)? Whats happening when the cell is absorbing energy?

Re: Galvanic Cell emf
When emf is negative, the cell does not "absorb energy". All this means is that the reaction would be unfavorable and thus non-spontaneous. Hope this helps.

Re: Galvanic Cell emf
If G is positive for a galvanic cell, the redox reaction is unfavorable, and therefore electrons would not flow from anode to cathode. In order for a battery to work, G must be negative so that you get a positive voltage and the electron flow from anode to cathode is favorable.
