Question

Could someone check if I calculated the right reaction orders to the prospective order of BR, BRO3-, and H+?
and please also help me
1. Determine the value of the rate constant for the formation of Br2.
2. Write the complete rate law expression for the formation of Br2. Name QUESTIONS I. Consider this reaction and the experimental quantities given in the table.

Explanation / Answer

Answer:-

Yes the order of reaction to the prospective order Br-, BrO3- and H+ , is correct.

So,

2. Rate law = k[Br-][BrO3-][H+]2

1. So, from the calculated concertrations,

(2.0 x 10-4) (2.0 x 10-4)(2.0 x 10-3)2 = k x 1.44 x 10-12

k = 1.6 x 10-13/1.44 x 10-12

k = 0.11 M-3.s-1
