Chemical Reaction Engineering For a tubular reactor with space time 'τ' and residence time 'θ', the following statement holds good. τ = θ , when the fluid density changes in the reactor τ = θ , for an isothermic tubular reactor in which the density of the process fluid is constant τ = θ , for a non-isothermal reactor τ and θ are always equal τ = θ , when the fluid density changes in the reactor τ = θ , for an isothermic tubular reactor in which the density of the process fluid is constant τ = θ , for a non-isothermal reactor τ and θ are always equal 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 1 0 2 3 1 0 2 ANSWER DOWNLOAD EXAMIANS APP
