A flask is charged with 0.124 mol of A and allowed to react to from B according to the reaction: A(g) -> B(g). the following drata are obtained for [A] as the reaction proceeds:
time: 0.00 10.0 20.0 30.0 40.0
moles of A: 0.124 0.110 0.088 0.073 0.054
A) what is the average rate of disapperance of A between 10s and 20s?
B) what is the avergae rate of disappearance of A between 20s and 40s?
C) what is the average rate of appearance of B between 20s and 30s?
D) How many moles of B are present at 10s?
E) how many moles of B are present at 30s?
