# Problem: For the reversible reactionA(g) ⇌ B(g) Which K value would indicate that there is more B than A at equilibrium?A. K = 9x10-9B. K = 0.2C. K = 9000D. K = 9x109

###### FREE Expert Solution

The equilibrium constant expression is written as:

$K=\frac{products}{reactants}$

$K = \frac{[B]}{[A]}$

For this problem, the expression should look as follows:
