Characteristics of Zero Order Reactions
Zero Order Reaction demonstrate the following characteristics:
- The rate of the reaction is not proportional to the reactant’s concentration.
- The reaction rate is related to the square of the reactant’s concentration.
- The natural logarithm of the reactant’s concentration determines the reaction rate, showing a proportional relationship.
- Situations leading to zero-order rates include a small fraction of reactant molecules being in a reactive state, constantly replenished, or when reactants have significantly different concentrations.
- Zero-order reactions are sometimes called pseudo-zero-order reactions due to being artifacts of specific reaction conditions.
Examples of Zero Order Reactions
Some Examples of zero-order reactions are:
- Reaction of Hydrogen with Chlorine (Photochemical Reaction)

- Decomposition of Nitrous Oxide over a Hot Platinum Surface
[Tex]2 \text{N}_2\text{O}(g) \rightarrow 2 \text{N}_2(g) + \text{O}_2(g)[/Tex]

- Constant Breakdown of Alcohol in the Liver
Zero Order Reaction
Zero Order Reaction is a type of chemical reaction where the reaction rate does not change with variations in the concentration of the reactants. In such reactions, the concentration rates remain constant over time. This type of reaction is characterized by the fact that the concentration of the reactants does not influence the reaction rate.
