Aperfectly mixed non-isothermal adiabatic reactor carries out a simple first-order exothermic reaction, aàbin the liquid phase. the product from the reactor is cooled from the output temperaturettotcand then introduced to a separation unit where the un-reactedais separated from the productb. the feed to the separation unit is split into two equal parts top product and bottom product. the bottom product from the separation unit contains 95% of the un-reactedain the effluent of the reactor and 1% ofbin the same stream. the bottom product which is at temperaturetc(since the separation unit is isothermal) is recycled and mixed with the fresh feed of the reactor and the mixed stream is heated to temperaturetfbefore being introduced to the reactor. write the steady state mass and energy balances for the whole process assuming constant physical properties and heat of reaction. discuss also the degree of freedom of the resulting model.
