Chemical Reaction Engineering MCQs

Pick out the correct statement.

Arrhenious equation represents graphically the variation between the __________ and temperature.

Helium-mercury method is used for the measurement of the __________ of the catalyst.

Sum of the powers of the concentration terms in the rate equation is called the __________ of the reaction.

The value of 'n' for a chemical reaction A → B, whose reaction rate is → CAn, will be __________ if the rate of the reaction increases by a factor of 8, when the concentration of is doubled.

The reaction A → B is conducted in an adiabatic plug flow reactor (PFR). Pure A at a concentration of 2 kmol/m3 is fed to the reactor at the rate of 0.01 m3/s and at a temperature of 500 K. If the exit conversion is 20%, then the exit temperature (in k) is (Data: Heat of reaction at 298 K = -50000 kJ/kmole of A reacted Heat capacities CPA = CPB = 100 kJ/kmole. K (may be assumed to be independent of temperature))

Variables affecting the rate of homogeneous reactions are

The reason why a catalyst increases the rate of reaction is that, it

A reversible liquid phase endothermic reaction is to be carried out in a plug flow reactor. For minimum reactor volume, it should be operated such that the temperature along the length
