Question

1. The reaction A --> B --> C has the rate equations.

r_A = 0.4 C_A, r_B = 0.3 C_B - 0.4 C_C

Three tanks of different sizes are available. At the desired production rate, the residence times of 5 min, 10 min and 15 min, are maintained in the successive stages of the CSTR battery. The feed concentrations are C_Ao = 0.9; C_Bo = 1.2 and C_Co = 0. Find the concentration of B in the effluent from each tank.

Answer 1

Formula's limitation is : we can use it only for first order reaction.

units of C_B1 will be same of C_B0
