Chemical Reaction Engineering For a __________ order reaction, the units of rate constant and rate of reaction are the same. Fractional Second Zero First Fractional Second Zero First 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 2/3 kW 5/3 kW 1kW 4kW 2/3 kW 5/3 kW 1kW 4kW ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Value of threshold energy decreases Collision frequency increases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Value of threshold energy decreases Collision frequency increases ANSWER DOWNLOAD EXAMIANS APP
