Question

The data in the table below were obtained for the reaction:

A + B -> P
Ex. # [A](M) [B](M) IR (M/s)
1 0.273 0.763 2.83
2 0.273 1.526 2.83
3 0.819 0.763 25.47
The rate law for this reaction is rate = ________
A) k [A] [B]
B) k [P]
C) k [A]2 [B]2
D) k [A]2
E) k [A]2 [B]

Answer 1

The rate law for the reaction is rate = k [A]^2 [B].

Step-by-step explanation:

The rate law for the given reaction can be determined by analyzing the data in the table. To do this, we compare the initial concentrations of reactants ([A] and [B]) with their respective initial rates (IR). By doing this, we can determine the order of reaction with respect to each reactant.

In this case, the rate law is rate = k [A]^2 [B], which means the answer is (E) k [A]^2 [B].
