For the reaction H(2)(g) + Br(2)(g) rarr...

For the reaction `H_(2)(g) + Br_(2)(g) rarr 2HBr (g)` the experimental data suggested that `r = k[H_(2)][Br_(2)]^(1//2)`
The molecularity and order of the reaction are respectively:

A

`2, 3//2`

B

`3//2, 3//2`

C

Not defined, `3//2`

D

`1, 1//2`

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)(g) + Br_(2) (g) rarr 2HBr(g)`
`r = K[H_(2)][Br_(2)]^(1//2)`
Molecularity rarr not defined, (`because` complete reaction)
order `= 1 + (1)/(2) =(3)/(2)`
