the reaction BrO3- + 3SO3 2- ---> has the rate law r= k[BrO3-][SO3 2-]. what is the order of the reaction with the respect to each reactant? wat s the overall order of the reaction?

BrO3- + SO32-

k [BrO3-] [SO3 2-]^3

To determine the order of the reaction with respect to each reactant and the overall order of the reaction, we can look at the coefficients in the balanced chemical equation.

The given balanced chemical equation is:
BrO3- + 3SO3 2- ---> (products)

The rate law is given as:
r = k[BrO3-][SO3 2-]

By comparing the coefficients in the balanced equation with the exponents in the rate law, we can determine the order of the reaction with respect to each reactant.

For BrO3-:
The coefficient of BrO3- in the balanced equation is 1, and there is no exponent specified in the rate law. Therefore, the order of the reaction with respect to BrO3- is 1.

For SO3 2-:
The coefficient of SO3 2- in the balanced equation is 3, and there is no exponent specified in the rate law. Therefore, the order of the reaction with respect to SO3 2- is also 1.

The overall order of the reaction is the sum of the orders with respect to each reactant. In this case, both the order with respect to BrO3- and SO3 2- is 1. Therefore, the overall order of the reaction is 1 + 1 = 2.

To determine the order of the reaction with respect to each reactant and the overall order of the reaction, you can use the method of initial rates. The order of a reactant is determined by how its concentration affects the rate of the reaction.

Let's denote the order of the reaction with respect to BrO3- as "m" and the order with respect to SO3 2- as "n". The overall order of the reaction is the sum of these two individual orders (m + n).

To find the order of the reaction with respect to BrO3-:
1. Conduct a series of experiments where the concentration of BrO3- is varied while keeping the concentration of SO3 2- constant.
2. Measure the initial rates of the reaction for each experiment.
3. If the concentration of BrO3- doubles and the rate also doubles, the reaction is first order with respect to BrO3-, i.e., m = 1.
4. If the concentration of BrO3- triples and the rate triples, the reaction is second order with respect to BrO3-, i.e., m = 2.
5. If the rate does not change when the concentration of BrO3- changes, the reaction is zero order with respect to BrO3-, i.e., m = 0.

Repeat the same steps to find the order of the reaction with respect to SO3 2- (n).

Once you have determined the values of m and n, the overall order of the reaction is the sum of those values (m + n).

Note: These values cannot be determined solely by examining the balanced equation; they must be experimentally determined.
