Question
Which of the following statement is true for the reaction H2 + Br2 → 2HBr. The rate law is 
= k[H2][Br2]1/2 :
= k[H2][Br2]1/2 :Options
A.order of reaction is 1.5
B.molecularity of the reaction is 2
C.by increasing the concentration of Br2 four times the rate of reaction is doubled
D.All the above are correct.
Solution
All the statements are correct,
Order of reaction = 1 +
= 1.5
molecularity = 1 + 1 = 2
α [Br2]1/2
So. reaction rate will be doubled if concenration of Br2 is increased by 4 times.
Order of reaction = 1 +
= 1.5molecularity = 1 + 1 = 2
α [Br2]1/2So. reaction rate will be doubled if concenration of Br2 is increased by 4 times.
