`K_C` for the reaction `2X leftrightarrow Y+Z` is `2 times 10^-3` at a given time the composition of reaction mixture `[X]=[Y]=[Z]=2.8 times 10^-4 M`. IN what direction, the reaction will proceed?

Explanation

Reaction quotient Q is given as, `Q=([Y][Z])/[X]^2= (2.8 times 10^-4 times 2.8 times 10^-4)/(2.8 times 10^-4)^2=1`
Since `Q gt K` the reaction proceeds in reverse direction.
