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 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 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering If the rate of a chemical reaction becomes slower at a given temperature, then the Initial concentration of the reactants remains constant Entropy changes Free energy of activation is lower Free energy of activation is higher Initial concentration of the reactants remains constant Entropy changes Free energy of activation is lower Free energy of activation is higher ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering Higher free energy of activation of a chemical reaction (at a given temperature) implies Both B and C Slower rate of reaction Higher equilibrium conversion Higher rate of reaction Both B and C Slower rate of reaction Higher equilibrium conversion Higher rate of reaction ANSWER DOWNLOAD EXAMIANS APP
