Chemical Reaction Engineering MCQ Questions & Answers | Chemical Engineering

In the converter of the contact process for the manufacture of H₂SO₄ the equilibrium conversion of SO₂ ____(i)____ with increase in temperature and ___(ii)___ with increase in the mole ratio of SO₂ to air.

The reaction A → B is conducted in an isothermal batch reactor. If the conversion of A increases linearly with holding time, then the order of the reaction 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

For the reaction, A + B → 2B + C,

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 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 stirred tank reactor compared to tubular-flow reactor provides
