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 reduced or the catalyst diffusivity is reduced Catalyst size is increased 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 reduced or the catalyst diffusivity is reduced Catalyst size is increased 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 If n = overall order of a chemical reaction. a = initial concentration of reactant. t = time required to complete a definite fraction of the reaction. Then pick out the correct relationship. T ∝ 1/an T ∝ an T ∝ 1/an - 1 T ∝ 1/an + 1 T ∝ 1/an T ∝ an T ∝ 1/an - 1 T ∝ 1/an + 1 ANSWER DOWNLOAD EXAMIANS APP
