Chemical Reaction Engineering MCQs

The order of a chemical reaction is

With increase in initial concentration, the fractional conversion of a first order reaction in a given time

Pick out the wrong statement:

The rate of the heterogenous catalytic reaction A(g) + B(g) → C(g) is given by $$ - {{\text{r}}_{\text{A}}} = \frac{{{\text{k}}.{{\text{K}}_{\text{A}}}.{{\text{p}}_{\text{A}}}.{{\text{P}}_{\text{B}}}}}{{1 + {{\text{K}}_{\text{A}}}.{{\text{P}}_{\text{A}}} + {{\text{K}}_{\text{C}}}.{{\text{p}}_{\text{C}}}}},$$ where KA and KC are the adsorption equilibrium constants. The rate controlling step for this reaction is

The knowledge of initial concentration and rate constant is necessary to determine the half life time of a reaction of __________ order.

The irreversible reaction, X → Y, is the special case of the reversible reaction, X ⇋ Y, in which the

Photo-chemical reactions occur in presence of

In an ideal mixed reactor (at steady state), the

An endothermic aqueous phase first order irreversible reaction is carried out in an adiabatic plug flow reactor. The rate of reaction
