Question

Consider the following hypothetical aqueous reaction: A (aq) ---> B (aq). A flask is charged with 0.065 mol of A in a total volume of 100.0 mL. The following data are collected: Time (min): 0 10 20 30 40 Moles of A: 0.065, 0.051, 0.042, 0.036 0.031 (a) Calculate the number of moles of B at each time in the table, assuming there are no molecules of B at time zero and that A cleanly converts to B with no intermediates. (b): calculate the avg rate of disappearance of A for each 10-min interval in units of M/s. (c): between t=10 min and t=30 min, what is the avg rate of appearance of B in units of M/s? Assume that the volume of the solution is constant Step by step please!!!

Explanation / Answer

Now,

Average rate of appearence of B

(0.029-0.014)/ (30-10)*60 = 1.25 X 10-3 mols/sec.

Time (min) A(moles) B (moles) 0 0.065 0 10 0.051 0.014 20 0.042 0.023 30 0.036 0.029 40 0.031 0.034
