Question

liquid phase reaction:
trityl (A) + methanol (B) -> product

a batch reactor was carried out at 25°C in excess solution (Cb0 = 0.5 mol/dm^3). The pyridine reacts with HCL, which then precipitates as pyridine hydrochloride making the reaction irreversible. the order of the reaction with respect to the methanol concentration (B) is order 1. The concentration of triphenyl methyl chloride (A) is measured as a function of time and is shown below. -ra = kCa x Cb

it is assumed that the value of Cb is almost always constant, or Cb = Cb0
-rA = kCb0 x CA^x
-rA = k1 x CA^x

 

use the integral method to ensure that the reaction is second order with respect to triphenyl methyl chloride
