2. A liquid reactant stream (1 mole/l) passes through two CSTRs in series operated at the same temperature. The concentration of A in the exit of the first reactor is 0.5 mole/l. Find the concentration in the exit stream of the second reactor for the following cases.

a. The reaction is first order with respect to A and the volume of reactors V2/V1=4.

b. The reaction is zero order with respect to A and V2/V1=0.7.

c. The reaction is second order
