For the reaction
`A+2Brarr2C`
the rate law for the formation of C is

A

`rate = k[A][B]^(2)`

B

`rate = k[A]^(2)[B]^(2)`

C

`rate = k[A][B]//[C]^(2)`

D

impossible to state from the stoichiometry of the reaction

Text Solution

Verified by Experts

The correct Answer is:
D
The rate law for an overall chemical reaction must be deterrmined experimentally. It can't be deduced from the stoichiometric coefficients in the balanced equation for the overall reaction because we cannot tell by merely looking at a balanced equaltion whether the reaction occurs as shown or in a series of steps. THis determination is made in the laboratory only.
