The rate of a certain chemical reaction is directly proportional to the square of the concetration of chemical A present and inversely proportional to the concetration of chemical B present. If the concetration of chemical B is increased by 100 percent, what is percent change in the concentration of chemical A required to keep the reaction rate unchanged?
