Chemical Reaction Engineering
For a heterogeneous catalytic reaction

The catalyst does not form an intermediate complex with the reactant
Free energy of activation is lowered in the presence of catalyst, which remains unchanged at the end of reaction
A relatively small amount of catalyst can cause the conversion of large amount of reactants which does not mean that catalyst concentration is important
The surface of the catalyst does not play an important role during reaction

Chemical Reaction Engineering
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.)

Reduced time (vt/V)
None of these
Reactor dispersion number (D/vL)
Thiele modulus (L√(k/D1)
