Increases the number of active centres by increasing the unevenness of catalyst surface and by creating discontinuities in the crystals All of these Atlers the position of equilibrium in a reversible reaction Initiates a chemical reaction and is a catalyst by itself Increases the number of active centres by increasing the unevenness of catalyst surface and by creating discontinuities in the crystals All of these Atlers the position of equilibrium in a reversible reaction Initiates a chemical reaction and is a catalyst by itself ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m³ and volumetric flow rate 1m³ /h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m³ . The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 kmole/m³ , the volume of the mixed flow reactor should be increased by a factor of 7 3 6 44015 7 3 6 44015 ANSWER DOWNLOAD EXAMIANS APP
