The reaction AB is carried out in a laboratory reactor. According to a published article the concentration of A should vary with time as follows: CA=CA0exp(kt) where CA0 is the initial concentration of A in the reactor and k is a constant. If CA and CA0 are in lbmoles/ft3 and t is in minutes, what are the units of k ? lbmolmin/ft3 min1 ft3lbmol/min min lbmol/ft3/min Which plot should yield a line if the proposed expression is correct? CAvsln(t)CAvs1/tln(CA)vs.tln(CA)vs.ln(t)CAvs.t The following data are taken for CA(t). Plot the data appropriately and use the method of least squares to estimate the following values. k=CAO=min1lbmol/ft3 Calculate the molarity of the mixture at t=237s. M=moles/L
