then =
It's because is negative, which places (RT) in the denominator. This is how the equation will now appear.
Here you can observe the value of is greater than

The number of moles of gas that move from the reactant side to the product side is denoted by the symbol ∆n or delta n in this equation.
Once more, n represents the growth in the number of gaseous molecules the equilibrium equation can represent. When there are exactly the same number of gaseous molecules in the system, n = 0, Kp = Kc, and both equilibrium constants are dimensionless.
<h3>Definition of equilibrium</h3>When a chemical reaction does not completely transform all reactants into products, equilibrium occurs. Many chemical processes eventually reach a state of balance or dynamic equilibrium where both reactants and products are present.

Answer : The correct option is, (A) 300.0 mL of 0.10 M CaCl₂
Explanation :
<u>(a) 300.0 mL of 0.10 M CaCl₂</u>
The dissociation reaction will be:
To calculate the number of moles of CaCl₂ as :
As, 1 mole of CaCl₂ contains ions = 3
So, 0.03 mole of CaCl₂ contains ions = 0.03 × 3 = 0.09 ions.
<u>(b) 400.0 mL of 0.10 M NaCl</u>
The dissociation reaction will be:
To calculate the number of moles of NaCl as :
As, 1 mole of NaCl contains ions = 2
So, 0.04 mole of NaCl contains ions = 0.04 × 2 = 0.08 ions.
<u>(c) 200.0 mL of 0.10 M FeCl₃</u>
The dissociation reaction will be:
To calculate the number of moles of FeCl₃ as :
As, 1 mole of FeCl₃ contains ions = 4
So, 0.02 mole of FeCl₃ contains ions = 0.02 × 4 = 0.08 ions.
<u>(d) 800.0 mL of 0.10 M sucrose</u>
The dissociation of sucrose is not possible because it is a non-electrolyte.
To calculate the number of moles of sucrose as :
As, 1 mole of sucrose contains ions = 1
So, 0.08 mole of sucrose contains ions = 0.08 × 1 = 0.08 ions.
Hence, the solutions contains the greatest number of ions is, 300.0 mL of 0.10 M CaCl₂
