Chemical Reaction Engineering For a tubular reactor with space time 'τ' and residence time 'θ', the following statement holds good. τ and θ are always equal τ = θ , for a non-isothermal reactor 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 and θ are always equal τ = θ , for a non-isothermal reactor 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 ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering With the same reaction time, initial concentration and feed rate, the reaction 2A → B is carried out separately in CSTR and P.F. reactor of equal volumes. The conversion will be Higher in P.F. reactor Higher in CSTR Same in both the reactors Data insufficient; can't be predicted Higher in P.F. reactor Higher in CSTR Same in both the reactors Data insufficient; can't be predicted ANSWER DOWNLOAD EXAMIANS APP
