Question

dx/dt=k[A ]^0.5 [B]^0.5 [C]^0.5 .what is order of the reaction

Answer 1

Hi,

I would think that you meant the overall order of the reaction.

If this is the case then the overall order of the reaction you can determine it by just adding the values 0.5 + 0.5 + 0.5 which gives an overall order as 1.5.

But also you can be required to get order of reaction with respect to each of the species i.e A, B and C in which case you have their values as each 0.5.

This question is mostly on chemicals in the determination of the rate of the reaction.

Answer 2

Answer: Order for the given reaction is 1.5

Explanation: Order of the reaction is defined as the sum of the exponents or powers to which the molar concentration in the rate law equation are raised to expresses the rate of the reaction.

We are given a rate of the reaction as:

$\frac{dx}{dt}=k[A]^{0.5}[B]^{0.5}[C]^{0.5}$

Order of the reaction is = 0.5 + 0.5 + 0.5 = 1.5
