(Kinetics Problem.)Consider a reaction that is negative order in reactant A –that is, the rate of reaction decreases as the reactant concentration increases. Briefly explain what might cause such a reaction rate dependence on the concentration of A. If you can think of more than one situation that might cause this, explain as many as you can think of.

Question

(Kinetics Problem.)

Consider a reaction that is negative order in reactant A –that is, the rate of reaction decreases as the reactant concentration increases. Briefly explain what might cause such a reaction rate dependence on the concentration of A. If you can think of more than one situation that might cause this, explain as many as you can think of.

Step 1

When the rate of a reaction is inversely affected by the concentration of the reactant, that is, increasing the reactant concentration decreases the rate of the reaction, then the reaction is termed as negative order reaction.

Step 2

An example of this reaction is the formation of oxygen molecule (O2) from ozone molecule (O3) and oxygen atom (O).

O+O3→2O2

In this reaction, as the concentration of oxygen atom increases, another reaction takes place which i...
