Question

What is the overall reaction order for the following rate law: rate = k [A]2[B]? A. zero B. first C. second D. third

Answer 1

The Answer, is A Hoped this helped

Answer 2

Answer: The correct answer is Option D.

Step-by-step explanation:

Rate law states that the rate of a reaction is directly proportional to the concentration of the reactants each raised to the power their stoichiometric coefficient which is determined experimentally and is known as order.

`Rate=k[A]^x[B]^y`

k = rate constant

x = order with respect to A

y = order with respect to B

n = x+y = Total order

For the given rate:
`k[A]^2[B]`

The order with respect to A is 2 and the order with respect to B is 1.

So, the total order of the reaction will be = (2 + 1) = 3

Hence, the correct answer is Option D.
