The rate law for a reaction is Rate = k[A]² . If the concentration of A is tripled, by what factor does the rate increa
Initial rate = k[A]², new rate = k(3[A])² = 9k[A]² . Factor = frac9k[A]²k[A]² = 9 . This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
