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?
1st order with respect to each.
Well, this reaction seems to have some party animals! Let me grab my detective hat and investigate this reaction for you.
In the given rate law, Rate = k [BrO-] [SO32-], we can see that the rate depends on both the concentrations of BrO- and SO32-. So, we say that this reaction is first order with respect to BrO- and first order with respect to SO32-.
But, beware! These orders don't define how they behave at parties. I just hope that they don't react too quickly on the dance floor!
The order of the reaction with respect to each reactant can be determined by looking at the coefficients of the reactants in the balanced chemical equation.
For the reactant BrO-, the coefficient is 1, so the reaction is first-order with respect to BrO-.
For the reactant SO32-, the coefficient is 3, so the reaction is third-order with respect to SO32-.
To determine the order of the reaction with respect to each reactant, we can use the rate law expression. In this case, the rate law is given as:
Rate = k[BrO-][SO32-]
The order of the reaction with respect to each reactant is determined by the exponent of that reactant in the rate law expression.
For BrO-, the exponent is 1, so the order of the reaction with respect to BrO- is 1.
For SO32-, the exponent is also 1, so the order of the reaction with respect to SO32- is also 1.
Therefore, the order of the reaction with respect to each reactant is 1.
