Answer: 
Explanation: For the given reaction:
![Kc=\frac{[Zn^+^2]}{[Ag^+]^2}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BZn%5E%2B%5E2%5D%7D%7B%5BAg%5E%2B%5D%5E2%7D)
Concentrations of the ions are not given so we need to think about another way to calculate Kc.
We can calculate the free energy change using the standard cell potential as:
can be calculated using standard reduction potentials.
Standard reduction potential for zinc is -0.76 V and for silver, it is +0.78 V.
= 
Reduction takes place at anode and oxidation at cathode. As silver is reduced, it is cathode. Zinc is oxidized and so it is anode.
= 0.78 V - (-0.76 V)
= 0.78 V + 0.76 V
= 1.54 V
Value of n is two as two moles of electrons are transferred in the cell reaction F is Faraday constant and its value is 96485 C/mol of electron .
= -297173.8 J
Now we can calculate Kc using the formula:
T = 25+273 = 298 K
R = 
--297173.8 = -(8.314*298)lnKc
297173.8 = 2477.572*lnKc
lnKc = 119.946
The factors that affect the rate of solution formation are capable of either increasing the rate of solution formation or decreasing it.
<h3>Factors that affect the rate of solution formation</h3>
The rate of solution formation from a chemical reaction depends on the following factors:
- Quantity of solute and solvent: The solute should be in less quantity and solvent should be more in quantity to dissolve the solute. This will enhance the formation of solution
- The size of the solute particles: When the solute particles are in smaller sizes, they react faster with the solvent to form solutions.
- The temperature of solvent: In increased temperature, the solute reacts faster with the solvent.
Therefore, the factors that affect the rate of solution formation are capable of either increasing the rate of solution formation or decreasing it.
