Decrease in inerts for an endothermic reaction ____
A. Increases conversion
B. Decreases conversion
C. Has no effect on conversion
D. Initially increases and then decreases conversion
The question was posed to me in an interview.
The origin of the question is RTD for Chemical Reactors in portion Distribution of Residence Time for Chemical Reactors of Chemical Reaction Engineering
The correct choice is B. Decreases conversion
The explanation is: Upon increasing inerts for an endothermic reaction, the curve shifts away faster from isothermal conditions. The conversion decreases and finally drops to zero as the inert concentration decreases.
