The reaction rate of the reaction H(2)(g...

The reaction rate of the reaction `H_(2)(g)+Br_(2)(g)rarr2HBr(g)` is given by `r=k[H_(2)][Br_(2)]^(1//2)`
Which of the following statement/is/are true ?

A

Order of reaction is 2

B

Molecularity of reaction is 2

C

Order of reaction is 1.5

D

Molecularity of reaction is 1.5

Text Solution

Verified by Experts

The correct Answer is:
B, C
`H_(2)(g)+I_(2)(g)rarr2HI(g)`
rate `=k[H_(2)[Br_(2)]^(1//2)`
Molecularity=2. Order `-1+1//2=3//2`
