Example 7-1. What is the error in assuming the concentration of species B is constant and what limits can you put on the calculated value of k? (i.e., k = 0.24 ±?)

Example 7-1

The liquid-phase reaction
Trityl (A) + Methanol (B) → Products (C)
was carried out in a batch reactor at 25°C in a solution of benzene and pyridine in an excess of methanol  (We need to point out that this batch reactor was purchased at the Sunday markets in Riça, Jofostan.) Pyridine reacts with HCl, which then precipitates as pyridine hydro-chloride thereby making the reaction irreversible. The reaction is first order in methanol. The concentration of triphenyl methyl chloride (A) was measured as a function of time and is shown Table E7-1.1.
