Rate of Reaction

Quick practice

Question 1 of 5

Reactant A decomposes by two simultaneous reactions to form two products one that is desired B and the other undesired product is C.

1) $A \stackrel{ k _{1}}{\rightarrow} B - r _{ A }= k _{1} C_{A}^{2}$

2) $A \stackrel{ k _{2}}{\rightarrow} C - r _{ A }= k _{2}$

The variation of selectivity with temperature is shown in the graph. The specific reaction rates are given at 300K and the activation energies of the reactions are $E _{1}=15,000 \ kcal / mol$ and $E _{2}=10,000 \ kcal / mol$ . What type of reactor should be used so that the selectivity of B can be maximized?
