Cyclohexane, c6h12, undergoes a molecular rearrangement in the presence of alcl3 to form methylcyclopentane, ch3c5h9, according to the equation:
c6h12 ⇌ ch3c5h9
if kc = 0.143 at 25°c for this reaction, find the equilibrium concentrations of c6h12 and ch3c5h9 if the initial concentrations are 0.200 m and 0. 075 m, respectively.

Explanation:

The given equilibrium reaction and the equilibrium concentrations are shown below as:-

The Kc of an equilibrium reaction measures relative amounts of the products and the reactants present during the equilibrium.

It is the ratio of the concentration of the products and the reactants each raised to their stoichiometric coefficients. The concentration of the liquid and the gaseous species does not change and thus is not written in the expression.

The expression for the Kc is:-

Given that:- Kc = 0.143

Thus, applying the values as:-

Thus,

The study of chemicals and bonds is called chemistry.

The correct answer is 0.03441 and 0.24059.

The Kc of an equilibrium reaction measures relative amounts of the products and the reactants present during the equilibrium.  It is the ratio of the concentration of the products and the reactants each raised to their stoichiometric coefficients.

The concentration of the liquid and the gaseous species does not change and thus is not written in the expression.

The formula used to solve the question is as follows;-

, the value of Kc in the question is 0.143

After putting the value in the equation.

After solving the question, the value of kc is.

Hence, the correct answer is 0.04059.
