Chemical Reaction Engineering For a tubular reactor with space time 'τ' and residence time 'θ', the following statement holds good. 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 τ and θ are always equal τ = θ , for a non-isothermal reactor ANSWER DOWNLOAD EXAMIANS APP
Chemical Reaction Engineering During manufacture of H₂SO₄, the oxidation of SO₂ to SO₃ by oxygen is an en- dothermic reaction. The yield of SO₃ will be maximised, if the Temperature is increased and pressure is reduced Temperature is reduced and pressure is increased Temperature is increased Pressure is reduced Temperature is increased and pressure is reduced Temperature is reduced and pressure is increased Temperature is increased Pressure is reduced ANSWER DOWNLOAD EXAMIANS APP
