The temperature of a heat exchanger, in a continuous stirred tank reactor, is increased suddenly from 100o C to 200o C, thereby causing the temperature of the reaction mixture to rise, from an initial steady temperature of 100 o C, at the rate of 0.5 deg C per second. Indicate graphically, the response of a thermometer placed in this reactor, given that its response approximates to a first order lag with a time constant of 8 s. Comment on any special features of this response.
