Question

What is the order of a reaction which has a rate expression; Rate = `"k"["A"]^(3/2)["B"]^1`?

Options

• 0

• `3/2 + 1`

• `3/2`

• 1

Answer 1

`3/2 + 1`

Explanation:

Order of a reaction may be defined as sum of the powers of the concentration of each reactant in the rate law expression.

Therefore, order of this reaction is = `3/2 + 1 = 5/2 = 2 1/2`
