Answer:
[tex][CH_3C_5H_9]=0.03441\ M[/tex]
[tex][C_6H_{12}]=0.24059\ M[/tex]
Explanation:
The given equilibrium reaction and the equilibrium concentrations are shown below as:-
[tex]\begin{matrix}&C_6H_{12}&\rightleftharpoons &CH_3C_5H_9\\ At\ time, t = 0 &0.200&&0.075\\At\ time, t=t_{eq}&-x&&+x\\ ----------------&-----&-&-----\\Concentration\ at\ equilibrium:-&0.200-x&&0.075+x\end{matrix}[/tex]
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:-
[tex]K_c=\frac{[CH_3C_5H_9]}{[C_6H_{12}]}[/tex]
Given that:- Kc = 0.143
Thus, applying the values as:-
[tex]0.143=\frac{0.075+x}{0.200-x}[/tex]
[tex]0.143\left(0.2-x\right)=0.075+x[/tex]
[tex]-0.143x=x+0.0464[/tex]
[tex]x=-0.04059[/tex]
Thus,
[tex][CH_3C_5H_9]=0.075+x=0.075-0.04059=0.03441\ M[/tex]
[tex][C_6H_{12}]=0.200-x=0.200-(-0.04059)=0.24059\ M[/tex]
The study of chemicals and bonds is called chemistry. When the amount of reactant and the product is equal, then is said to be an equilibrium state.
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.
What is Hydrocarbon?
- The chemical compound which is only made of carbon and hydrogen is called hydrocarbon.
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;-
[tex]K_c =\frac{CH_3C_5H_9}{C_6H_12}[/tex]
The value of Kc in the question is 0.143.
After putting the value in the equation.
[tex](0.143)(0.2-x)=0.075+x[/tex]
After solving the question, the value of kc is 0.04059.
Hence, the correct answer is 0.04059.
