# Answer the following: Equilibrium constant of the reaction, 2Cu(aq)+→Cu(aq)2++Cu(s) is 1.2 × 106. What is the standard potential of the cell in which the reaction takes place? - Chemistry

Sum

Answer the following:

Equilibrium constant of the reaction,

2"Cu"_(("aq"))^+ -> "Cu"_(("aq"))^(2+) + "Cu"_(("s")) is 1.2 × 106.

What is the standard potential of the cell in which the reaction takes place?

#### Solution

Given: Equilibrium constant of the reaction (K) = 1.2 × 106.

To find: Standard potential of cell ("E"_"cell"^circ)

Formulae: ("E"_"cell"^circ) = (0.0592 "V")/"n"  log_10 "K"

Calculation:

For the given reaction, n = 1.

Using formula,

("E"_"cell"^circ) = 0.0592/1 xx log_10 (1.2 xx 10^6)

("E"_"cell"^circ) = 0.0592 xx (6.079) = 0.36 V

The standard cell potential of cell is 0.36 V.

Is there an error in this question or solution?
