Quizplus · Accepted Answer

If the rate constant for the reaction in the direction of the formation of B is 100 times greater than for the reaction in the direction of A formation, the formation of B will be the favored direction. Therefore, when the reaction reaches equilibrium, there will be substantially more B than A present in the reaction vessel.
