Chemical Reaction Engineering The rate of the chemical reaction A → B doubles as the concentration of A i.e.., CA is doubled. If rate of reaction is proportional to CAn, then what is the value of n for this reaction? 0.5 2 1 0.5 2 1 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering A second order reaction of the form A + B → C is called a pseudo-first order reaction, when CB0 ≥ CB0 CB0 > CA0 CA0 = CB0 CA0 > CB0 CB0 ≥ CB0 CB0 > CA0 CA0 = CB0 CA0 > CB0 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In an exothermic reaction, the energy of the reacting substances as compared to that of products is Same More Less Either A or B, depends on order of reaction Same More Less Either A or B, depends on order of reaction 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 3 7 44015 6 3 7 44015 6 ANSWER DOWNLOAD EXAMIANS APP
