For the equilibrium `CH_(3)-CH_(2)-CH_(2)-CH_(3)(g)hArrCH_(3)-overset(CH_(3))overset(|)underset(H)underset(|)(C)-CH_(3)(g)` equilibrium constant is found to be `1.732` at `298K`. Now if in a vessel at `298K`, a mixture of these two gases be taken as represented by the point `P` in the figure, predict what will hapen

Options

A. (A) Immediately, above equilibrium will be setup
B. (B) Above reaction will go in the forward direction till it attains equilibrium.
C. (C) Above reaction will go in the backward direction till it attains equilibrium
D. (D) Nothing can be said

Answer

C

Explanation

From given information, `Q=tan 75^(@)=("conc. Of isobu tan e")/("conc. Of n-butan e")gtK_(c)=sqrt3`
so backward reaction
