The reaction
BrO- + 3SO32- → Br- + 3SO42-
has the rate law, Rate = k[BrO-][SO32-]
a. What is the order of the reaction with respect to each reactant?
3. Balance the following reaction:
MnO4- +
The reaction
BrOˉ + 3SO₃²ˉ → Brˉ +3SO₄²ˉ
Has the rate, Rate = k[BrOˉ] [SO₃²ˉ]
What is the order of the reaction with respect to each reactant?
None
First order
The order of the reaction with respect to BrOˉ is 1. The order of the reaction with respect to SO₃²ˉ is also 1. Since the sum of the orders with respect to each reactant gives the overall order of the reaction, 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, we can use the method of initial rates.
1. Choose two experiments with different initial concentrations of one reactant while keeping the concentration of the other reactant constant.
Let's say we have Experiment 1 with initial concentrations [BrO3-]_1 and [SO3 2-]_1, and Experiment 2 with initial concentrations [BrO3-]_2 and [SO3 2-]_2. In both experiments, we measure the initial rate of the reaction (r_1 and r_2, respectively).
2. Write the rate law using the given information.
The rate law for the reaction is given as r = k[BrO3-][SO3 2-].
3. Compare the rate expressions from each experiment.
From Experiment 1: r_1 = k[BrO3-]_1[SO3 2-]_1
From Experiment 2: r_2 = k[BrO3-]_2[SO3 2-]_2
Dividing these two equations, we get:
r_1/r_2 = ([BrO3-]_1[SO3 2-]_1)/([BrO3-]_2[SO3 2-]_2)
= ([BrO3-]_1/[BrO3-]_2) * ([SO3 2-]_1/[SO3 2-]_2)
4. Analyze the ratio of concentrations.
If the ratio of concentrations ([BrO3-]_1/[BrO3-]_2) is equal to the ratio of rates (r_1/r_2) and the same holds true for [SO3 2-], then the reaction is first order with respect to both reactants. If the ratio is different, the reaction is not first order with respect to that reactant.
5. Determine the overall order of the reaction.
The overall order of the reaction is the sum of the orders with respect to each reactant.
In this case, since the given rate law is r = k[BrO3-][SO3 2-], and we found that the reaction is first order with respect to both reactants, the overall order is:
Overall order = 1 + 1 = 2
Therefore, the order of the reaction with respect to each reactant is both 1, and the overall order of the reaction is 2.
