Calculate the orders of each ion. Choose the correct rate law.
Rate = k[BrO₃⁻]1[Br⁻]1[H₃O⁺]2
Rate = [Br⁻]1[BrO₃⁻]1[H₃O⁺]2
Rate = k[H₃O⁺][BrO₃⁻][Br⁻]
Rate = k[BrO₃⁻]2[Br⁻]2[H₃O⁺]1
Rate = -k[BrO₃⁻]1[Br⁻]1[H₃O⁺]2
What is a pseudo-rate law?
A rate law that is false
A rate law that is result of the simplification of a more complex rate law
A rate law that is incomplete, due to lacking orders
A rate law that represents the abstract concept of rate laws (Rate = k[A][B]), without specific reactants or orders
A rate law that does not have any variables calculated
What is a Reaction Mechanism?
The initial product and the final reactants solely
The intermediate substances of a reaction solely
The mechanism by which reactions occur; activation energy
The series of steps a reaction takes to go from reactant to product
Which of the following Rate Laws are Bimolecular?
Rate = [A]
Rate = k[A]2
Rate = k[A][B][C]
Rate = k[A][B]
Rate = [A]2[B]2
How does one calculate the Overall Reaction Order?
(a)
Which is the Differential Rate Law for the equation A₂ + 2B → 2AB?
Rate = k[A₂][B]2
Rate = k[AB]n
Rate = k[A₂]n[B]n
Rate = k[AB]2
Rate = [A₂]n[B]n
