Which statement is correct regarding the rate of the reaction below? 3A + B 4X + 2Y The rate of disappearance of B is three times greater than that of A. The rate of formation of Y is twice the rate of formation of X. The rate of formation of X is four times the rate of disappearance of B. The rate of disappearance of A is three times the rate of formation of Y.

First, let's write the givens in the form of a chemical equation:

3A + B ... > 4X + 2Y

Now we find that this equation implies the following:

For every 4X and 2Y formation, 3A and 1B must disappear (react).

Comparing this implication to the above choices, we find that the right answer is: The rate of formation of X is four times the rate of disappearance of B.
