Question #c7e45

Answer 1

`E_(Zn-Cu) = 1.1.091v @ 25^oC` (Non-Standard Conditions). Typically, calculation of Galvanic Cell Potentials are based upon data published in Reduction Potential Tables at `25^oC` not `15^oC`.

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:

Answer 2

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

Answer 3

Comparing EMF for Zn/Cu Galvanic Cell at 15 deg-C and 25 deg-C.
