A CSTR is to be designed in which an exothermic liquid phase first order reaction of the type, , is taking place. The reactor is to be provided with a jacket in which coolant is flowing. Following data is given: = 5 kmole/m ; = 0.5; Feed temperature = reactor temperature = 40°C. Rate constant at 40°C = 1 min ; (Δ) = - 40kJ/mole; ρ = 1000kg/m = 4 J/gm.°C ; = 10 m/min (ρ and are same for the reactant and product streams). The amount of heat to be removed is

• A. 2/3 kW
• B. 1kW
• C. 5/3 kW
• D. 4kW
