Correct answer: B. Reaction has a tendency to go in backward direction.

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.
