2. Monobutylphthalate and butanol react in the presence of H₂SO₄ forming dibutylphthalate and water. Reaction can be carried out in the continuous stirred tank reactor (CSTR). The reactants are placed in two separate tanks containing 0.4 mol/liter of monobutylphthalate and 2 mol/liter of butanol and fed to the reactor under 10 liter/h and 30 liter/h, respectively. The reactants are mixed before entering the reactor. The reaction rate constant is k = liter/(mol.min). Calculate the CSTR volume when conversion is 60%. (Reaction rate expression:   (20%)
