Chemical Reaction Engineering Batch process is preferred over continuous process, when the Same equipment can not be used for several processes of the same nature Sales demand of product is not steady Product yields and quality can not be achieved in continuous process, because of long residence time All of these Same equipment can not be used for several processes of the same nature Sales demand of product is not steady Product yields and quality can not be achieved in continuous process, because of long residence time All 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 Both A & B Pressure Neither A nor B Temperature Both A & B Pressure Neither A nor B Temperature ANSWER DOWNLOAD EXAMIANS APP
