Chemical Reaction Engineering In a zero order reaction, reactants concentration does not change with time and the Reaction rate is trebled when the initial concentration is trebled Time for completion of the reaction is independent of the initial concentration Time for half change is independent of the initial concentration Time for half change is half the time taken for completion of the reaction Reaction rate is trebled when the initial concentration is trebled Time for completion of the reaction is independent of the initial concentration Time for half change is independent of the initial concentration Time for half change is half the time taken for completion of the reaction ANSWER DOWNLOAD EXAMIANS APP
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." Inner catalyst core of radius R/2 does not participate in reaction Inner catalyst core of radius 7R/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 R/8 does not participate in reaction Inner catalyst core of radius R/2 does not participate in reaction Inner catalyst core of radius 7R/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 R/8 does not participate in reaction ANSWER DOWNLOAD EXAMIANS APP
