A feed stream of 0.7m3/h containing 1.8kmolA/m3 at steady state operation passes through an isothermal continuous stirred tank reactor which has a volume of 3m3. Only one irreversible reaction takes place in the reactor and the reaction rate is given by: rA=1+0.1cA20.3cA0.2(kmolAreacted/m3h) If the reactor volume does not change with time a) Derive the transfer funtion between inlet and outlet concentration of reactant A b) Determine the concentration of the residual A at time after 15 min the inlet concentration is decreased by 5% and its final steady state value
