For a reaction, $A + B ⟶$ product, it is found that rate law is $r = k [A]^{1.5} [B]^{2.5}$ . What is the order of reaction?

Options:

Answer:

Solution:

The rate law for the reaction is given as $r = k [A]^{1.5} [B]^{2.5}$ .

The overall order of a reaction is the sum of the exponents of the concentration terms in the rate law expression.

Order of reaction $= 1.5 + 2.5 = 4$ .

Answer: $4$
