Solved: A flask is charged with 0.100 mol of A and allowed
Chapter 6, Problem 20E(choose chapter or problem)
A flask is charged with 0.100 mol of A and allowed to react to form B according to the hypothetical gas-phase reaction A()
B (
) . The following data are collected:
__________________________________________________________________________
Times (s) 0 40 80 120 160
__________________________________________________________________________
Moles of A 0.100 0.67 0.045 0.030 .020
(a) Calculate the number of moles of B at each time in the table, assuming that A is cleanly converted to B with no intermediates. (b) Calculate the average rate of disappearance of A for each 40-s interval in units of mol/s . (c)What additional information would be needed to calculate the rate in units of concentration per time?
