What is the purpose of a catalyst
a catalyst provides a different path for a reaction to occur
To lower the activation energy of a reaction
What are m and n in the rate law equation
They are experimentally determined exponents
What causes pressure changes of reactants to affect the reaction rate
The frequency of collisions is changed.
How does increasing the temperature affect collisions
It increases the number of high-energy collisions
Which of the following acts as a catalyst in catalytic converters
How is the effect of concentration changes on the reaction rate seen in the rate law
The exponents determine how much concentration changes affect
the reaction rate
Why does a reaction slow down with time
The reactant concentrations decrease
What would happen to the rate of a reaction with rate law kNO2H2 if the concentration of NO were doubled
the rate would be four times larger. apex
What is the rate constant of a reaction if rate 1 10-2 molLs A is 2 M B is 3 M m 2 and n 1
Which has the largest rate constant k
What information does an energy diagram give
It shows the energy requirements needed in order for a reaction
to occur.
What is the rate of a reaction if the value of k is A and B are each 2 M
What is a rate law
An equation that relates the reaction to the concentrations of the reactants
