Question
Consider the reaction: A + B -> products From the following data obtained at a certain temperature,determine the order of the reaction and calculate the rateconstant. [A] (M) [B] (M) Rate (M/s) 1.50 1.50 3.20 x 10^-1 1.50 2.50 3.30 x 10^-1 3.00 1.50 6.40 x 10^-1 So, I can see the rate doubled at the 3 experiment. So Iwould take one trial M and divide by another trial M, and thendivide one trial rate by another trial rate. Repeat this so Ido it for A and B. Not sure how to end it with theinformation you get.

Explanation / Answer
We Know that : The given reactionis : A + B -------> Products From the given experimental data : Divide trial 1 by trial 3 we get : ( 1 / 2 )a = 1 /2 a = 1 Divide trial 1 by trial 2 we get : (0.6 )b = 0.96 b = 0.08 Rate = K [A] [B]0.08 K = 0.20652 K = 0.20652
