Question

Which has equilibrium constant as one?

• A. 1 only
• B. 2 only
• C. both 2 and 3
• D. both 1 and 3

Answer 1

Answer: (B)

2 only

Answer 2

${{K}_{eq}}=$ Equilibrium constant is the ratio of concentration of product to reactant so.
$K_{eq}=\frac{[P]}{[R]}$ and $P$ and $R$ should be equal then $K_{eq}$ would be constant. The graph show $K_{eq}=$ constant because $R = P$.
