Chapter 11, Problem 4QAP

Consider the following hypothetical reaction:

${\text{2AB}}_2\left(g\right)\to {\text{A}}_2\left(g\right)+2{\text{B}}_2\left(g\right)$A 500.0-mL flask is filled with 0.384 mol of AB₂. The appearance of A₂ is monitored at timed intervals. Assume that temperature and volume are kept constant. The data obtained are shown in the table below.

(a) Make a similar table for the disappearance of AB₂.

(b) What is the average rate of disappearance of AB₂ over the second and third 10-minute intervals?

(c) What is the average rate of appearance of A₂ between $t=30$ and $t=50$?
