${E}_{Z n - C u} = 1.1 .091 v \circ {25}^{o} C$ (Non-Standard Conditions). Typically, calculation of Galvanic Cell Potentials are based upon data published in Reduction Potential Tables at ${25}^{o} C$ not ${15}^{o} C$.

#### Explanation:

Using the Nernst Equation and Standard Reduction Potentials for Zinc and Copper, the following is given as method for determining Galvanic Cell Potential at Non-Standard Conditions:

Correction to cell notation...
$\text{Zn(s)/Zn"^(+2)[0.020M]//Cu^(+2)"[0.01M]/Cu(s)}$
Reduced form of Copper should be at end of notation.
