Chemical Reaction Engineering For a tubular reactor with space time 'τ' and residence time 'θ', the following statement holds good. 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 τ and θ are always equal 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 CSTR Data insufficient; can't be predicted Higher in P.F. reactor Same in both the reactors Higher in CSTR Data insufficient; can't be predicted Higher in P.F. reactor Same in both the reactors ANSWER DOWNLOAD EXAMIANS APP
