- The reason why a catalyst increases the rate of reaction is that, it
- A reversible liquid phase endothermic reaction is to be carried out in a plug flow reactor. For minimum reactor volume, it should be operated such that the temperature along the length
- __________ catalytic reaction is involved in the thermal cracking of gas oil.
- A gaseous reactant is introduced in a mixed reactor of 3 litres volume at the rate of 1 litre/second. The space time is __________ seconds.
- In the reversible reaction of the type, A + B ⇋ AB, in general
- Which of the following is not a dimension-less group used in catalysis ? (where, D = dispersion co-efficient, cm² /sec.D1 = diffusion co-efficient; cm²/sec L = length of the reactor, cm t = time, sec, v = volumetric flow rate, cm³/sec . V = volume, cm³.)
- Holding time for flow reactors is __________ the space time, for constant fluid density
-
Given,
3H₂ + CO = CH₄ + H₂O, KP = 101.84 and,
4H₂ + CO₂ = CH₄ + 2H₂O, KP = 101.17
the KP for the reaction CO + H₂O = CO₂ + H₂ is - Rate of a chemical reaction is not affected by the
