Chemical Reaction Engineering For a first order isothermal chemical reaction in a porous catalyst, the effectiveness factor is 0.3. The effectiveness factor will increase if the Catalyst size is increased or the catalyst diffusivity is reduced Catalyst size is reduced or the catalyst diffusivity is reduced Catalyst size is increased or the catalyst diffusivity is increased Catalyst size is reduced or the catalyst diffusivity is increased Catalyst size is increased or the catalyst diffusivity is reduced Catalyst size is reduced or the catalyst diffusivity is reduced Catalyst size is increased or the catalyst diffusivity is increased Catalyst size is reduced or the catalyst diffusivity is increased ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In a zero order reaction, reactants concentration does not change with time and the Time for half change is independent of the initial concentration Time for half change is half the time taken for completion of the reaction Time for completion of the reaction is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled Time for half change is independent of the initial concentration Time for half change is half the time taken for completion of the reaction Time for completion of the reaction is independent of the initial concentration Reaction rate is trebled when the initial concentration is trebled ANSWER DOWNLOAD EXAMIANS APP
