Chemical Reaction Engineering A CSTR is to be designed in which an exothermic liquid phase first order reaction of the type, A → R, is taking place. The reactor is to be provided with a jacket in which coolant is flowing. Following data is given: CA0= 5 kmole/m³ ; XA = 0.5; Feed temperature = reactor temperature = 40°C. Rate constant at 40°C = 1 min⁻¹ ; (ΔH) = - 40kJ/mole; ρ = 1000kg/m³ CP = 4 J/gm.°C ; q = 10⁻³ m³/min (ρ and CP are same for the reactant and product streams). The amount of heat to be removed is 1kW 5/3 kW 2/3 kW 4kW 1kW 5/3 kW 2/3 kW 4kW ANSWER DOWNLOAD EXAMIANS APP
