Answer
There will be a large amount of unreacted starting material at equilibrium. This reaction is not likely to be a good source of products at this temperature.
Work Step by Step
Looking at the K expression:
$$K = \frac{[Products]}{[Reactants]}$$
When the equivalent value of a fraction is large, the numerator is much bigger than the denominator. Therefore [Products] >>> [Reactants].
If K is small, the reactants concentration is much larger than the concentration of products.
