Question

A) The above reactor is adibatic. ( True or false? If false, why?) B) The above reaction is exothermic with a reactor that has a constant cooling temperature (Ta= constant). ( True or false? If false, why?) C) The above reaction is endothermic with a reactor that has a constant heating temperature (Ta= constant). ( True or false? If false, why?) A reversible reaction takes place in some sort of non-isothermal reactor. The following profiles describe the temperature, conversion, and possible equilibrium conversion along the length of the PBR. Only one of the follow statements can be true, describe the physical reason why two of the following statements are false. Use only the information provided in each statement. Do not make extra assumptions. xe

Explanation / Answer

A false: This is not adiabatic because its not following the uniform pattern of temperature. in case of adiabatic

(no heat is added or remove). if its temperature is decreasing it should continue to do so. if its Temperature is increasing it should continue to increase. In this case Temperature is first decrease then increase means not following the uniform pattern so it is false.

B False: in case of exothermic reaction when temperature is increasing the equilibrium conversion should decrease . but in this case from graph when temperature is increasing, equilibrium conversion is also increasing so it is false.

C True. In endo thermic when temerature increase equilibrium conversion also increase. when temperature decrease equilibrium conversion also decrease. so true
