# What is zeroth order kinetics?

## What is zeroth order kinetics?

Zero order kinetics is a way of describing how the body uses and breaks down some medicines. While the rate at which the body eliminates most drugs is proportional to the concentration administered, known as first order kinetics, drugs that work by zero order kinetics work at a predictable, constant rate.

What is a zeroth order reaction?

: a chemical reaction in which the rate of reaction is constant and independent of the concentration of the reacting substances — compare order of a reaction.

How do you find the zero order reaction?

The integrated rate law for the zero-order reaction A → products is [A]_t = -kt + [A]_0. Because this equation has the form y = mx + b, a plot of the concentration of A as a function of time yields a straight line. The rate constant for the reaction can be determined from the slope of the line, which is equal to -k.

### What is a zero order reaction give an example?

Reaction in which concentration of the reactants do not change with time and the concentration rates remain constant throughout are called zero order reactions. A→Product. Example: H2​+Cl2​hv ​2HCl.

What is the meaning of zero order kinetics?

Zero order kinetics refers to chemical reactions whose rate of the reaction does not depend on the reactant concentration. In other words, the concentration of reactants does not affect the rate of the reaction.

What is zero order and first order kinetics?

First Order Kinetics: First order kinetics refers to chemical reactions whose rate of reaction depends on the molar concentration of one reactant. Zero Order Kinetics: Zero order kinetics refers to chemical reactions whose rate of the reaction does not depend on the reactant concentration.

## What is zero order reaction rate?

Zero order. For zero-order reactions, the reaction rate is independent of the concentration of a reactant, so that changing its concentration has no effect on the speed of the reaction. Thus, the concentration changes linearly with time.

What are the units of zero order reaction?

The rate law for a zero-order reaction is rate = k, where k is the rate constant. In the case of a zero-order reaction, the rate constant k will have units of concentration/time, such as M/s .
