For a first order chemical reaction in a porous catalyst, the Thiele modulus is 10. The effectiveness factor is approximately equal to

In which of the following reactions the equilibrium will shift to the right, if the total pressure is increased?

An example of autothermal reactor operation is

The performance of a cascade of CSTR's can be improved by adding

For identical flow rate, feed composition and for elementary first order reactions, 'N' equal sized mixed reactors in series with a total volume 'V' gives the same conversion as a single plug flow reactor of volume 'V' for constant density systems. This is true, when the value of 'N' is

Rate of a chemical reaction is independent of the concentration of the reactants for a __________ reaction.

Kinetics of a solid catalysed reaction can best be studied in a __________ reactor.

The rate of the reaction, X → Y, quadruples when the concentration of 'X' is doubled. The rate expression for the reaction is, r = K Cxn, the value of 'n' in this case will be
