Chemical Reaction Engineering "A spherical porous catalyst particle of radius R is subjected to reactant A which reacts to form B by a zero order surface reaction A → B. Film mass transfer resistance is negligible and pore diffusion of A is rate controlling. The effectiveness factor of the catalyst is reported as 7/8. Which of the following statement is true?A. Inner catalyst core of radius R/8 does not participate in reaction." Ffectiveness factor for a zero order reaction can not be 7/8 as it must always be 1 Inner catalyst core of radius 7R/8 does not participate in reaction Inner catalyst core of radius R/2 does not participate in reaction Inner catalyst core of radius R/8 does not participate in reaction Ffectiveness factor for a zero order reaction can not be 7/8 as it must always be 1 Inner catalyst core of radius 7R/8 does not participate in reaction Inner catalyst core of radius R/2 does not participate in reaction Inner catalyst core of radius R/8 does not participate in reaction ANSWER DOWNLOAD EXAMIANS APP
