Chemical reaction rate of a component depends upon the______________________?
Correct answer: A. All A., B. and C.
- A. All A., B. and C.
- B. Temperature of the system
- C. Pressure of the system
- D. Composition of the component only
Explanation
Reaction rate is affected by composition through concentrations or partial pressures and by temperature through the rate constant; pressure also matters directly for gas-phase reactions. Hence all three listed operating variables may affect the rate.

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_________________?
