Question

The rate of the reaction between compound A and compound B was studied at 20°C. The following data were collected.

Trial   Initial Concentration of A (M)   Initial Concentration of B (M)   Measured Initial Rate (M/s)
1   0.15   0.15   3.0 × 10−4
2   0.30   0.15   6.0 × 10−4
3   0.15   0.30   6.0 × 10−4

 

(a)   What is the reaction order for compound A?
Answer with a whole number like 0, 1, 2, or 3
   
(b)   >What is the reaction order for compound B?
Answer with a whole number like 0, 1, 2, or 3
   
(c)  

What is the rate law for this reaction?
Mark the letter corresponding to the correct response from the choices below:

A   rate = k
B   rate = k[A]
C   rate = k[A]2
D   rate = k[A]3
E   rate = k[B]
F   rate = k[B]2
G   rate = k[B]3
H   rate = k[A][B]
I   rate = k[A]2[B]
J   rate = k[A]3[B]
K   rate = k[A][B]2
L   rate = k[A][B]3
   
(d)   What is the value of the rate constant k for this reaction?
