In the reaction of metallic cobalt placed in nickel sulphate solution,...
The reaction of metallic cobalt in a nickel sulfate solution involves a competition for the release of electrons. This means that the cobalt metal can react with the nickel ions in the solution, or the nickel can deposit on the cobalt metal.
At equilibrium, the reaction has balanced out with no net change in the concentration of the reactants and products. The fact that both Ni+2 (aq) and Co+2 (aq) are present at moderate concentrations at equilibrium signifies that neither forward nor reverse reactions are greatly favoured.
- A: This option is incorrect because both reactants and products are present in moderate concentrations, indicating that neither is greatly favoured.
- B: This statement is not correct either. Even though Co (s) and Ni+2 (aq) are part of the reaction, the fact that Co+2 (aq) is also present at moderate concentrations shows that they are not the only favoured species.
- C: This option is also incorrect. Even though Co+2 (aq) and Ni (s) are part of the reaction, the fact that Ni+2 (aq) is also present at moderate concentrations shows that they are not the only favoured species.
- D: This is the correct answer. When a reaction is at equilibrium, it means that the rate of the forward reaction equals the rate of the reverse reaction. Therefore, neither the reactants nor the products are greatly favoured. In other words, the concentrations of the reactants and products remain constant over time

In the reaction of metallic cobalt placed in nickel sulphate solution,...
Explanation:
When metallic cobalt is placed in nickel sulphate solution, the following reaction occurs:
Co(s) + NiSO4(aq) → Ni(s) + CoSO4(aq)
In this reaction, both cobalt and nickel ions compete for release of electrons from the metallic cobalt. At equilibrium, chemical tests reveal that both Ni2+(aq) and Co2+(aq) are present at moderate concentrations, which means that neither the reactants nor the products are greatly favoured.
Reasons why option 'D' is correct:
• Equilibrium is reached
At equilibrium, the forward and reverse reactions occur at the same rate. This means that the concentrations of the reactants and products remain constant over time. Therefore, the reaction is in a state of equilibrium.
• Both reactants and products are present
Since the reaction is at equilibrium, both the reactants (cobalt and nickel sulphate) and the products (nickel and cobalt sulphate) are present in moderate concentrations. This means that neither the reactants nor the products are greatly favoured.
• Dynamic nature of equilibrium
It is important to note that even though the concentrations of the reactants and products remain constant at equilibrium, the reaction is still ongoing. This is because the reactants are continuously reacting to form products and vice versa.
