Question

The reaction out in a laboratory reactor. According to a published article t concentration of A should vary with time as follows: CA-CAO Cxp(-hp) where CAo is the initial concentration of A in the reactor and k is a constant. (a) If CA and CAO are in Ib-moles/ft' and r is in minutes, what are the units of (b) The following data are taken for CA(1):

Answer 1

Explanation:

CAo = [1.285567172 lb-mol x (1000/2.2046) g/lb ] / (3.048 dm)3

= 14.73215273 M

k = 0.4137 min-1 = 0.4137/60 = 0.006895 s-1

.: CA = 14.73215273 x e-0.006895(t)

At t = 265 sec

CA = 2.37 M
