The rate of a certain chemical reaction is directly proportional to the square of the concentratin of chemical A present
and inversely proportional to the concentration of chemical B present. If the concentration of chemical B is increased by
100 present,which of the following is clostest to the percent change in the conceratration of chemical A required to keep the reaction rate unchanged?
(A)100% decrease
(B)50% decrease
(C)40% decrease
(D)40% increase
