Q5. A 100.0mL flask is filled with 0.124 moles of A and allowed to react to form B according to the reaction
below. The following experimental data are obtained for amount of A as the reaction proceeds.
3A(g)->2B(g)
a. How many moles of B are present at 10.0 second?
b. What is the average rate of appearance of B between t=10.0sec. and t=30.0 sec.? Assume that
the volume of the flask is constant.
