Question

In a concentration cell, the reaction is driven by: Select the correct answer below:

a. K
b. Q
c. E*cell
d. all of above

Answer 1

b. Q

Step-by-step explanation:

Equilibrium constant K is a measure of the ratio of the equilibrium concentration of the products of a reaction to the equilibrium concentration of the reactants with each concentration raised to the power corresponding to the coefficient in the balanced equation of the reaction.

On the other hand , the
`E^\theta_(cell)` is the standard electrode potential of the right-hand electrode minus the standard electrode potential of the left hand electrode, Thus,
`E^\theta_(cell)` will be zero if concentration cell in the two electrodes appears to be the same.

The Nernst equation correlates the cell E.M.F to a standard value E and the activities of the species that takes places in the cell reaction. Thus in a concentration cell, the reaction is driven by Q
