Question
If the rate law for a reaction is rate = k[A]^2[B]: What is the overall order of the reaction? If the concentration of A is doubled and the concentration of B is tripled, how will this affect the rate of the reaction? How will doubling the concentration of B while holding A constant affect the value of k (assuming that temperature remains constant)? What four factors influence the rate of a homogeneous reaction? A reaction between the substances A and B has been found to give the following data: 3A + 2B rightarrow 2C + D Using the above data, determine the order of the reaction with respect to A and B, and the rate law. Using the information given in the Background and Procedure, complete the table below and copy the results into your lab notebook for use during lab.Explanation / Answer
2a) Rate = k [A]2[B]= k [A]2[B]1
Overall Order 2 +1 = 3
2b) If [A] = [2A] and [B] = [3B]
Then rate = [2]2[3]1 = 4 x 3 = 12 times increase.
2c) If [A] = [A] and [B] = [2B]
then rate = [1]2[2]1 = 2 times increase.
3.)
4) Rate = [A]2[y]3
as increasing concentration of A (Keeping B constant) two times, reaction rate increaseses 2 times.
and increasing concentration of B (Keeping A constant) two times, reaction rate increaseses 27 times
So, over all rate = 2 +3 = 5.
