The following data are for the kinetics scheme: AB;rB=k1CAAaD;rD=k2CA Assuming that reaction occurs in a constant-volume batch reactor at a fixed temperature, and that at time zero only A and B are present (CAO=0.1mol/L and CBO=0.04mol/L). Calculate k1/k2 if the CA=0.036mol/L and CB=0.088mol/L at 40min. 2 0.3 4 3 1.5
