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

the reaction was mass transfer limited at 500 rpm

the reaction was mass transfer limited at 300 rpm

the reaction did not involve any mass transfer step

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

If the stirring speed increased from 300 to 500 rpm leads to an increa
