Consider the voltaic cellzn(s) + cu{2+}(> zn{2+}(aq)+cu(s){}=chargeunder standard conditions, what is the maximum electrical work, in joules that can accomplish if 60 g of copper is plated out?

Max. work done in 60 g of copper plated out is 200472.14 J

Explanation:

Given cell reaction is:

Standard reduction potential of Zn electrode () is 0.763 V.

Standard reduction potential of Cu electrode () is -0.337 V.

Copper acts as cathode and Zinc acts as anode.

Cell potential (E) = E° cathode - E° anode

                           = 0.763 - (-0.337)

                           = 1.10 V

formula for the work done is as follows:

Here, n is no. of electron involved in the reaction.

F(Faraday's constant) = 96500

In the given reaction, n = 2

Therefore, 212300 J work is done by reducting 1 mol of copper.

Copper given is 60 g.

Molecular mass of copper is 63.54 g/mol.

Max. work done in 60 g of copper plated out is:

< > according to newton's third law of motion, forces always act in equal but opposite pairs. another way of saying this is for every action, there is an equal but opposite reaction.< >
