Answer:
If we consider the equilibrium constant expression you can easily predict the answer. Suppose the equilibrium reaction is as follows:
A(g) + B(g) <------> C(g) + D(g)
K = [C][D] / [A][B]
Now, if K >>>1 this means that numerator is much more greater than denominator. That is, you have more C and D than A and B. Most of the reactants are converted to the products. The forward reaction is more effective.
If K <<<1 this means that denominator is much more greater than numerator. That is, you have more A and B than C and D. A small portion of the reactants are converted to the products. The reverse reaction is more effective.
