Chemical Reaction Engineering If in the gaseous phase reaction, N₂O₄ ⇋ 2NO₂, x is the part of N₂O₄ which dissociates, then the number of molecules at equilibrium will be (1 - x)² (1 + x)² (1 + x) (1 - x) (1 - x)² (1 + x)² (1 + x) (1 - x) ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A first order gaseous phase reaction is catalysed by a non-porous solid. The kinetic rate constant and the external mass transfer co-efficients are k and kg respectively. The effective rate constant (keff) is given by keff = (k+ kg)/2 1/keff = 1/k + 1/kg keff = (kkg)1/2 keff = k + kg keff = (k+ kg)/2 1/keff = 1/k + 1/kg keff = (kkg)1/2 keff = k + kg ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Calcination reaction of limestone (CaCO₃ → CaO + CO₂) goes to completion in the rotary kiln, because Of high calcination temperature CO₂ escapes continuously CaO is more stable than CaCO₃ CaO is not dissociated Of high calcination temperature CO₂ escapes continuously CaO is more stable than CaCO₃ CaO is not dissociated 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 4kW 1kW 2/3 kW 5/3 kW 4kW 1kW 2/3 kW 5/3 kW ANSWER DOWNLOAD EXAMIANS APP
