Chemical Reaction Engineering I Set 1

For an ideal plug flow reactor, the value of Peclet number is

If the time required for half change is inversely proportional to the square of initial concentration and the velocity depends on the units in which the concentration term is expressed, then the order of reaction is

If 'n' is the order of reaction, then unit of rate constant is

A first order reaction requires two equal sized CSTR. The conversion is

Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is

An irreversible first order reaction is being carried out in a CSTR and PFR of same volume. The liquid flow rates are same. The relative conversion will

Organic catalysts differ from the inorganic catalyst in the sense that the former is

For a fluidised bed reactor, the most suitable/relevant model is a __________ model.

Which of the following is not a unit of reaction rate?

Overall rate of reaction in a heterogenous catalytic reaction depends upon the mass and energy transfer from the fluid to solid surface and its rate of reaction is usually __________ the concentration of catalyst, if it does not entail a chain mechanism.
