Standard Cell Potential

Postby Jarrett Peyrefitte 2K » Wed Feb 26, 2020 4:24 pm

What is a standard cell potential? How do you calculate it given the half-reactions for the cell and the standard potential?

Standard electric potential is the electric potential of a galvanic cell measured under standard conditions. How to calculate: E(cell) = E(cathode) - E(anode). You can get E(cathode) and E(anode) from the half reactions that happen at the cathode and anode.

In addition, a substance is in standard conditions when it has a molarity of 1M (aq), when it has a partial pressure of 1 bar (g), or when it can be considered a pure liquid or solid.

In addition ,The relative reactivities of different half cells can be used to compare the direction of electron flow. A higher means there is a greater tendency for reduction to occur, while a lower one means there is a greater tendency for oxidation to occur.
