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 , for an isothermic tubular reactor in which the density of the process fluid is constant τ = θ , when the fluid density changes in the reactor τ and θ are always equal τ = θ , for a non-isothermal reactor τ = θ , for an isothermic tubular reactor in which the density of the process fluid is constant τ = θ , when the fluid density changes in the reactor ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering In an ideal P.F.R. at steady state conditions There is no lateral mixing of fluid The composition of reactants remains constant along a flow path The conversion of the reactant varies from point to point along a flow path There may be diffusion along the flow path There is no lateral mixing of fluid The composition of reactants remains constant along a flow path The conversion of the reactant varies from point to point along a flow path There may be diffusion along the flow path ANSWER DOWNLOAD EXAMIANS APP
