Answer: The standard cell potential (E∘) for the reaction 
is -0.121 V
Explanation:
The reaction is:
Relation between standard Gibbs free energy and equilibrium constant follows:
where,
= Standard Gibbs free energy = ?
R = Gas constant = 
T = temperature = 298 K
K= equilibrium constant = 
Putting values in above equation, we get:
To calculate standard Gibbs free energy, we use the equation:
Where,
n = number of electrons transferred = 1
F = Faradays constant = 96500 C
= standard cell potential = ?
Putting values in above equation, we get:
Thus standard cell potential (E∘) for the reaction is -0.121 V

Physical changes are changes that change the physical traits of the substance, without making any change in their internal structure. Chemical changes effect internal structure of the substance and new substance is formed.
Examples of physical changes - breaking glass, evaporating alcohol, shredding paper...
Chemical : burning paper, heating sugar to form caramel, rusting of iron...
