Given the chemical reaction: Hg2+(aq) + Cu(s) + Hg(s) + Cu2+(aq)
When the reaction reaches equilibrium, the cell potential will be
1
-0.51 V
2.
0.00 V
3.
0.51 V
4.
1.19 V

When the reaction reaches equilibrium, the cell potential will be 0.00 V

Explanation:

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.

The standard emf of a cell is related to Gibbs free energy by following relation:

The Gibbs free energy is related to equilibrium constant by following relation:

For equilibrium

Thus

Thus When the reaction reaches equilibrium, the cell potential will be 0.00 V

Option 2: 0.00V

Explanation:

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
