Answer 1

Answer:

In a solution, we have 1 mole of A, 1 mole of B and 2 mole of C. Find the mole fraction of each of them.

Explanation:

Correct option is

B

0.066

A(g)+B(g)⇌C(g)molesatt=011.52ateqbm1+x1.5+x2−x

QC=(1.5)(1.7)127=1.33

Reaction will be backward as concentration of C is less at equilibrium than at initial.

Keq=[A][B][C]=[1+1.5][1.5+1.5][0.5]=[2.5][3][0.5]=0.0666[∵2−x=0.5⟹x=0.5]

As QC>Keq thus reaction will go in the backward direction.
