Learning Goal:
To learn how to use the Nernst equation.
Part A
The standard reduction potentials listed in any
reference table are only valid at the common
reference temperature of 25 °C and standard
conditions of 1 M for solutions and 1 atmn for
gases. To calculate the cell potential at
nonstandard conditions, one uses the Nernst
equation,
What is the value for the reaction quotient, Q, for the cell?
Express your answer numerically.

R=8.314 J/(K- mol) is the gas constant, T is
the temperature in kelvins, n is the number of
moles of electrons transferred,
F = 96, 500 C/(mol e) is the Faraday
constant, and Q is the reaction quotient.
