Problem 2
Give an example from everyday experience of (a) a very fast reaction, (b) a moderately fast reaction, and (c) a slow reaction.
Problem 3
What is a homogeneous reaction? What is a heterogeneous reaction? Give examples.
Problem 6
The rate of hardening of epoxy glue depends on the amount of hardener that is mixed into the glue. What factor affecting reaction rates does this illustrate?
Problem 10
How does an instantaneous rate of reaction differ from an average rate of reaction?
Problem 12
Explain how the initial instantaneous rate of reaction can be determined from experimental concentration versus time data.
Problem 13
What are the units of reaction rate? What is the sign of a reaction rate?
Problem 15
What are the units of the rate constant for (a) a firstorder reaction, (b) a second-order reaction, and (c) a zero-order reaction?
Problem 16
How does the dependence of reaction rate on concentration differ between a zero-order and a first-order reaction? Between a first-order and second-order reaction?
Problem 18
If the concentration of a reactant is doubled and the reaction rate is unchanged, what must be the order of the reaction with respect to that reactant?
Problem 20
If the concentration of a reactant is doubled, by what factor will the rate increase if the reaction is second order with respect to that reactant?
