- Pick out the wrong statement.
- The effectiveness factor for large value of Thiele modulus (L√(K/D1)) of a solid catalysed first order reaction is equal to (where, L = length of the reactor, cm, D1 = diffusion co-efficient, cm²/second)
- The performance equations for constant density systems are identical for
- 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
- __________ is the controlling step in a highly temperature sensitive fluid-solid non-catalytic reaction.
- Space time in flow reactor is
- Space velocity
- The residence time distribution of an ideal CSTR is
-
To maximise the formation of R in the simultaneous reaction
A + B → R , rR = 2CA0.5.CB2
A + B → S , rS = 1.5 CA . CB
We should have - The rate constant of a reaction depends on the
|
A.
Exit age description function (E) and internal age distribution function (I) are related as,E = - dI/d0 .# |
|
B.
Chmisorption studies are useful in the determination of catalyst surface area and pore size distribution |
|
C.
A higher temperature favours the reaction of higher activation energy |
|
D.
A catalyst increases the potential energy barrier over which the reactants must pass to form products |
