Agitation and Aeration - Medical Science

Q1:

If the stirring speed increased from 300 to 500 rpm leads to an increase in the reaction rate by two folds. Then it may be concluded that

A the reaction was mass transfer limited at 300 rpm

B the reaction was mass transfer limited at 500 rpm

C the reaction did not involve any mass transfer step

D the movement of molecules in the reactor at 300 rpm occurred due to diffusion alone

ANS:A - the reaction was mass transfer limited at 300 rpm
