For the reaction 2 ~A B + C , K _ C =4 10⁻³ . At a given time, the composition of reaction mixture is: [ A ]=[ B ]=[ C ]=2 10⁻³ M . Then, which of the following is correct?

Step-by-step solution

2 ~A B + C , K _ C =4 10⁻³ At a given time t , Qc _ c is to be calculated and been compared with K _ c . aligned & Q _ C = [ B ][ C ] [ A ]^2 = (2 10⁻³ ) (2 10⁻³ ) (2 10⁻³ )^2 & Q _ C =1 aligned As Q_c _c , so reaction has a tendency to move backward.
