Consider this equilibrium reaction at 400 k. br2(g)+cl2(g)↽−−⇀2brcl(g)kc=7.0 br 2 ( g ) + cl 2 ( g ) ↽ − − ⇀ 2 brcl ( g ) k c = 7.0 if the composition of the reaction mixture at 400 k is [brcl]=0.004150 [ brcl ] = 0.004150 m, [br2]=0.003660 [ br 2 ] = 0.003660 m, and [cl2]=0.0006720 [ cl 2 ] = 0.0006720 m, what is the reaction quotient, q ?

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:-

The expression for the reaction quotient is:-

Given,

So,

The reaction quotient is:- 7.00238
