Answer:
The reaction quotient is:- 7.00238
Explanation:
The reaction quotient of an equilibrium reaction measures relative amounts of the products and the reactants present during the course of the reaction at particular point in the time.
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 equation is as follows:-
[tex]Br_2_{(g)} +Cl_2_{(g)}\rightleftharpoons 2BrCl_{(g)}[/tex]
The expression for the reaction quotient is:-
[tex]Q=\frac{[BrCl]^2}{[Br_2][Cl_2]}[/tex]
Given,
[tex][BrCl]=0.004150\ M[/tex]
[tex][Br_2]=0.003660\ M[/tex]
[tex][Cl_2}]=0.0006720\ M[/tex]
So,
[tex]Q=\frac{(0.004150)^2}{0.003660\times 0.0006720}==7.00238[/tex]
The reaction quotient is:- 7.00238
The reaction quotient gives the ratio of the concentration of the product and the reactant at a particular time in the reaction. The reaction quotient of the reaction at equilibrium is 7.00238.
What is equilibrium?
The equilibrium is given as the condition at which the rate of reaction is constant.
The reaction quotient for the given reaction raised to the stoichiometric coefficient is given as:
[tex]Q=\rm \dfrac{[BrCl]^2}{[Br_2][Cl_2]} \\\\\textit Q=\dfrac{(0.004150)^2}{(0.003660)(0.0006720 )} \\\\\textit Q=7.00238[/tex]
The reaction quotient of the reaction is 7.00238.
