Question

In the figure shown below reactant $A$ (represented by the square) is in equilibrium with product $B$ (represented by circle). The equilibrium constant is:

• A. $1$
• B. $2$
• C. $8$
• D. $4$

Answer 1

The correct option is B $2$

Let us assume the equation to be $A\rightleftharpoons B$,
Number of particles of $A=6$
Number of particles of $B=11$
$K=\frac{11}{6}\approx 2$
