Chemical Reaction Engineering Photochemical reaction rate does not depend significantly on temperature, because It is a reversible reaction The energy of reacting molecules exceeds the activation energy by absorption of light It is an exothermic reaction None of these It is a reversible reaction The energy of reacting molecules exceeds the activation energy by absorption of light It is an exothermic reaction None of these ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering If the catalyst pore size is small in comparison with the mean free path, collisions with the pore wall controls the process'. The diffusivity under this condition is called 'Knudsen diffusivity', which is affected by the Pressure Both A & B Temperature Neither A nor B Pressure Both A & B Temperature Neither A nor B ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering For identical flow rate, feed composition and for elementary first order reactions, 'N' equal sized mixed reactors in series with a total volume 'V' gives the same conversion as a single plug flow reactor of volume 'V' for constant density systems. This is true, when the value of 'N' is ∞ ≥1 1 >1 ∞ ≥1 1 >1 ANSWER DOWNLOAD EXAMIANS APP
