Chemical Reaction Engineering If helium is introduced in a reactor containing O₂, SO₂ and SO₃ at equilibrium, so that total pressure increases while volume and temperature remains constant. In this case the dissociation of SO₃ (as per Le Chatlier principle) Remains unaltered Decreases Increases Changes unpredictably Remains unaltered Decreases Increases Changes unpredictably ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering An irreversible aqueous phase reaction, A + B → P, is carried out in an adiabatic mixed flow reactor. A feed containing 4kmole/m³ of each A and B enters the reactor at 8m³ /hr. If the temperature of the exit stream is never to exceed 390 K, what is the maximum inlet feed temperature allowed?(Data: Heat of reaction = - 50 kJ/mole, Density of the reacting mixture = 1000kg/m³, Specific heat of reacting mixture = 2kJ/kg.K)The above data can be assumed to be independent of temperature and composition. 490 390 190 290 490 390 190 290 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering 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 First increases and then decreases Increases Decreases Is at the highest allowable temperature throughout First increases and then decreases Increases Decreases Is at the highest allowable temperature throughout ANSWER DOWNLOAD EXAMIANS APP
