Final answer:
The Nernst equation is used to calculate cell potential under nonstandard conditions by incorporating the reaction quotient, Q.
Step-by-step explanation:
To find the cell potential under nonstandard conditions, one must use the Nernst equation. This equation incorporates the reaction quotient, Q, and allows for the calculation of cell potential when concentrations, pressure, or temperature deviate from standard conditions. Here's the Nernst equation in its general form:
Ecell = E°cell - (RT/nF) ln Q
Where Ecell is the cell potential under nonstandard conditions, E°cell is the standard cell potential, R is the universal gas constant, T is the temperature in Kelvin, n is the number of moles of electrons transferred in the redox reaction, F is Faraday's constant, and Q is the reaction quotient.
