Chapter 13, Problem 10E

Consider the reaction.

${\text{2H}}_{\text{2}}{\text{O}}_{\text{2}}(ag)\to 2{\text{H}}_{\text{2}}\text{O}(l){\text{+O}}_{\text{2}}(g)$

This graph shows the concentration of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ as a function of time.

Use the graph to calculate:

a. The average rate of the reaction between 10 and 20 s.

b. Theinstantanous rate of the reaction at 30 s.

c. The instantaneous rate of formation of ${\text{O}}_{\text{2}}$ at 50 s.

d. If the initial volume of the ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is 1.5 L, what total amount of ${\text{O}}_{\text{2}}$ (in moles) forms in thefirst 50 s of roaction?
