Problem 24P
By what factor does the rate in Problem 16.26 change if each of the following changes occurs: (a) [BrO3?] is doubled; (b) [Br ?] is halved; (c) [H+] is quadrupled?
ANSWER:
Solution 24P
Here we have to find out by what factor does the rate change in each of the following rate law equation,
Step 1
(a) [BrO3-] is doubled;
For 1st order reaction, the rate law equation can be written as,
Rate = k [BrO3-]1
In this question it has been given that [A] is doubled than rate law becomes,
Rate = k [2 BrO3-]1
= 21 = 2
Thus the rate increases by 2 or rate is double.
