The gas phase reaction 2A ⇋ B is carried out in an isothermal plug flow reactor. The feed consists of 80 mole % A and 20 mole % inerts. If the conversion of A at the reactor exit is 50%, then CA/CA0 at the outlet of the reactor is 43959 43833 43864 43898 TRUE ANSWER : ? YOUR ANSWER : ?
For nearly isothermal operation involving large reaction time in a liquid-phase reaction, the most suitable reactor is a __________ reactor. Batch Fixed bed Stirred tank Tubular flow TRUE ANSWER : ? YOUR ANSWER : ?
The rate of a homogeneous reaction is a function of Pressure and composition only All of these Temperature and composition only Temperature and pressure only TRUE ANSWER : ? YOUR ANSWER : ?
The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Increased temperature reduces the activation energy Fraction of molecules having threshold energy increases Value of threshold energy decreases Collision frequency increases TRUE ANSWER : ?
