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/8 does not participate in reaction Inner catalyst core of radius R/2 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/8 does not participate in reaction Inner catalyst core of radius R/2 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 ANSWER DOWNLOAD EXAMIANS APP

Chemical Reaction Engineering For all positive reaction orders for a particular duty, Ratio of the volume of the mixed reactor to that of the plug-flow reactor decreases with order Density variation during reaction affects design Mixed reactor is always larger than the plug-flow reactor Reactor size is independent of the type of flow Ratio of the volume of the mixed reactor to that of the plug-flow reactor decreases with order Density variation during reaction affects design Mixed reactor is always larger than the plug-flow reactor Reactor size is independent of the type of flow ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In an ideal P.F.R. at steady state conditions There is no lateral mixing of fluid The composition of reactants remains constant along a flow path There may be diffusion along the flow path The conversion of the reactant varies from point to point along a flow path There is no lateral mixing of fluid The composition of reactants remains constant along a flow path There may be diffusion along the flow path The conversion of the reactant varies from point to point along a flow path ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For reactions in parallel viz A → P (desired product) and A → Q (unwanted product), if the order of the desired reaction is higher than that of the undesired reaction, a Both A and B Tubular reactor is preferred over a single CSTR for high yield Single CSTR is the most suitable Batch reactor is preferred over a single CSTR for high yield Both A and B Tubular reactor is preferred over a single CSTR for high yield Single CSTR is the most suitable Batch reactor is preferred over a single CSTR for high yield ANSWER DOWNLOAD EXAMIANS APP
