Question

State True or False.

The effect of a change in the concentration of a reactant or product on the cell voltage can be predicted by applying Le-chateliers principle.

• A. True
• B. False

Answer 1

The correct option is A True

According to Nernst equation:
$E=E^o-0.0591logQ/n$
So according to Le-chateliers principle. if conc of reactant increases then value of Q will increases and E will decreases means reaction moves backward.
So effect of a change in the concentration of a reactant or product on the cell voltage can be predicted by applying Le-chateliers principle.
