The acid-catalyzed irreversible liquid-phase reaction:
A → B
carried out adiabatically in a CSTR. The reaction is second order in A. The feed, which is equal molar in water (containing the catalyst) and A, enters the reactor at a temperature of 52°C and a total volumetric flow rate of 10 dm^3/min. The concentration of A entering the reactor is 4 M. Vo = 10 dm^3 /min, Cao = 4 mol/dm^3, To = 325K.
(a) What is the reactor volume to achieve 80% conversion?
(b) What conversion can be achieved in a 1000 dm^3 CSTR?
What is the exit temperature?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
