If the concentration of A at the centre of the pellet is much less than at the external surface, the process is limited by Reaction Diffusion within the pellet None of these External mass transfer Reaction Diffusion within the pellet None of these External mass transfer ANSWER DOWNLOAD EXAMIANS APP
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 4kW 2/3 kW 1kW 5/3 kW 4kW 2/3 kW ANSWER DOWNLOAD EXAMIANS APP
