4 cards from this section. Quick, good the night before a test.
What is meant by the term reaction order?
Think about how concentration affects reaction speed.
Can the order of a reaction be zero?
Consider examples like constant rate reactions.
What is the order of a reaction where the rate depends on the concentration of one reactant squared?
Think about how you add the exponents.
True or False: Molecularity can be a fraction.
Consider how many species collide in an elementary step.
For a reaction with a rate law Rate = k[A]^2[B], if the concentration of A is doubled and the concentration of B is halved, what is the new rate compared to the original rate?
Follow the changes in concentration using the original rate expression.
A zero-order reaction has a rate constant of 0.04 M/s. What will be the concentration of the reactant after 10 seconds if the initial concentration was 1 M?
Remember the zero-order reaction formula relates concentration decrease to time.
