Question

please answer asap

What is the standard cell potential of an electrochemical cell?

the standard electrode potential of the anode, relative to a hydrogen cell
the difference between the standard electrode potential of the two half-cells
the standard electrode potential of the cathode, relative to a hydrogen cell
the sum of standard electrode potential of the two half-cells

Answer 1

Answer:

The correct answer is the difference between the standard electric potential of the two half cells.

Explanation:

Cell potential of an electro chemical cell can be defined as the difference between the reduction potential of the negatively charged electrode or cathode and reduction potential of the positively charged electrode or cathode.

              E0 cell= Eo cathode - E0 anode

If the E0 cell of an ion is positive then that ion will have high tendency to gain electron thereby acting as an oxidant.On the hand if an ion has negative E0 then that ion will have high tendency to donate electron thereby acting as reducing agent.

Answer 2

Answer:

The difference between the standard electrode potential of the two half-cells.
