9. Explain the difference between the rate law a reaction and the integrated rate law for a reaction. What relationship does each kind of rate law express?
10. Write integrated rate laws for zero-order, first-order, and second- order reactions of the form A → products.
11. What does the term half-life mean? Write the expressions for the half-lives of zero-order, first-order, and second-order reactions.
45. Indicate the order of reaction consistent with each observation.
a. A plot of the concentration of the reactant versus time yields a straight line.
b. The reaction has a half-life that is independent of initial concentration.
c. A plot of the inverse of the concentration versus time yields a straight line.
51. This reaction was monitored as a function of time:
A plot of In[A] versus time yields a straight line with slope -0.0045/s.
a. What is the value of the rate constant (k) for this reaction at this temperature?
b. Write the rate law for the reaction.
c. What is the half-life?
d. If the initial concentration of A is 0.250 M, what is the concentration after 225 s?
