Chemical Reaction Engineering Brunaur, Emmet and Teller (BET) equation is used to determine the specific surface area of a porous particle but not the pore volume & the porosity of the catalyst bed. Which of the following postulates is not used to derive BET equation? Langmuir The adsorbed layer may be polymolecular in thickness and the heat of adsorption in each layer (except the first one) is involved in each of the evaporation process None of these There is no dynamic equilibrium between successive layer Langmuir The adsorbed layer may be polymolecular in thickness and the heat of adsorption in each layer (except the first one) is involved in each of the evaporation process None of these There is no dynamic equilibrium between successive layer ANSWER DOWNLOAD EXAMIANS APP

Chemical Reaction Engineering Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is 3 2 1 0 3 2 1 0 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering The half life period of a first order reaction is Always the same irrespective of the reaction Dependent on initial concentration of the reactants Proportional to the initial concentration of reactants Half the specific rate constant Always the same irrespective of the reaction Dependent on initial concentration of the reactants Proportional to the initial concentration of reactants Half the specific rate constant ANSWER DOWNLOAD EXAMIANS APP
