What is a zero-order reaction?
Understand the Problem
The question is asking about zero-order reactions, which are a type of chemical reaction where the rate of reaction is constant and does not depend on the concentration of reactants. This suggests that the user is looking for information about this type of chemical reaction, including its characteristics and examples.
Answer
A zero-order reaction's rate does not change with reactant concentration.
A zero-order reaction is a chemical reaction in which the rate of reaction remains constant and does not change with the concentration of the reactants.
Answer for screen readers
A zero-order reaction is a chemical reaction in which the rate of reaction remains constant and does not change with the concentration of the reactants.
More Information
In a zero-order reaction, the rate is equal to the rate constant, and the reaction typically depends on a specific condition, like surface area or catalyst saturation. The integrated rate law is [A]_t = -kt + [A]_0, represented as a straight line. The graph of concentration vs. time is a straight line.
Tips
A common mistake is assuming that a zero-order reaction's rate increases with increasing reactant concentration, which is not true. It's crucial to remember that the rate is constant and does not depend on reactant concentration.
