Question

For the equilibrium CH3 – CH2 – CH2 – CH3(g) equilibrium constant is found to be 1.732 at 298 K. Now if in a vessel at 298 K, a mixture of these two gases be taken as represented by the point P in the figure, predict what will happen

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

Answer 1

Answer: (C)

Above reaction will go in the backward direction till it attains equilibrium

Answer 2

From given information,

$Q = \tan{}75^{0} = \frac{conc.ofisobu\tan e}{conc,ofn - bu\tan e} > K_{C} = \sqrt{3}$

so backward reaction
