A flask is charged with 0.124 mol of A and allowed
to react to form B according to the reaction A(g)
B(g). The following data are obtained
for A as the reaction proceeds:
The average rate of disappearance of A between 20.0 s and 40.0 s is ________ mol/s
Select one:
A. 1.4 × 10–3
B. 7.1 × 10–3
C. 8.5 × 10–4
D. 1.7 × 10–3
E. 590
Homework Answers
Average rate of disappearance between 20 s to 40s=[A]final - [A]initial /Time
=(0.054 - 0.088)/(40-20)
=1. 7 × 10^-3 mol/s
So option (D) is correct
Thank you and please thumbs up
