For a reaction : A + B rarr Products, ...

For a reaction : `A + B rarr` Products,
The rate law expression is, rate `= k[A]^(1//3)[B]^(2)`
What is the order of a reaction ?

Text Solution

Verified by Experts

The rate law expression is,
rate `= k[A]^(1//3)[B]^(2)`
`therefore` Order of reaction `= (1)/(3) + 2 = 2(1)/(3)`
