- The energy balance equation over a tubular reactor under transient conditions is
- Brunaur, Emmet and Teller (BET) equation is used to determine the specific surface area of a porous particle but not the pore volume & the porosity of the catalyst bed. Which of the following postulates is not used to derive BET equation?
- A space velocity of 5 hr⁻¹ means that
- An isothermal irreversible reaction is being carried out in an ideal tubular flow reactor. The conversion in this case will __________ with decrease in space time.
- For multiple reactions, the flow pattern within the vessel affects the
- If helium is introduced in a reactor containing O₂, SO₂ and SO₃ at equilibrium, so that total pressure increases while volume and temperature remains constant. In this case the dissociation of SO₃ (as per Le Chatlier principle)
- The temperature dependence of reaction rate constant (K) by Arhenius law is given by
- Consider the 'n' th order irreversible liquid phase reaction A → B. Which one of the following plots involving half life of the reaction (t1/2) and the initial reactant concentration (CA0) gives a straight line plot?
- For a tubular flow reactor with uniform concentration and temperature, the independent variable is
- A chemical reaction, A → 3B, is conducted in a constant pressure vessel. Starting with pure A, the volume of the reaction mixture increases 3 times in 6 minutes. The fractional conversion is
