Chemical Kinetics - Formulas conc [A] All rates written as time or t Instantaneous rate is the slope of a concentration vs time plot and is d[A] shown by the differential equation: dt Overall rates for forward reactions are shown as POSITIVE rates d[A] therefore all reactants (which have negative rate of change) must have their rates |
How to memorize simple formulas on chemical kinetics?
Try to memorize the Simple Formulas on Chemical Kinetics provided as they form a stronger base during your study. 1. Rate of Reaction in the form of a Chemical reaction: m 1 A + m 2 B + ……… → n 1 P + n 2 Q + n 3 R + …….. 2. Unit of Rate constant: 3. First order reaction: 4. Second Order Reaction: Case: (i) When concentration of A and B taking same.
What does k mean in chemistry?
The constant k is the rate constant of the reaction, and is a measure of how fast or slow the reaction is. It depends on the reaction itself (the chemical compounds A and B) and environmental factors such as temperature. The rate constant does not depend on the concentrations of the species involved in the reaction.
Why is chemical kinetics important?
Chemical kinetics, also called reaction kinetics, helps us understand the rates of reactions and how it is influenced by certain conditions. It further helps to gather and analyse information about the mechanism of the reaction and define the characteristics of a chemical reaction.
What is the difference between chemical kinetics and rate of reaction?
Chemical kinetics is the study of the rate at which chemical reactions occur. It helps us understand the factors affecting these rates, the mechanism of the reaction, and the sequence of events that lead to the formation of products. Rate of Reaction is the change in concentration of reactants or products per unit time.

Chemical kinetics, also called reaction kinetics, helps us understand the rates of reactions and how it is influenced by certain conditions. It further helps to gather and analyse information about the mechanism of the reaction and define the characteristics of a chemical reaction. byjus.com
Rate of Formations and Disappearances
In any chemical reaction, as the reaction proceeds, the amount of reactants decreases, whereas the amount of products increases. One has to understand that the rate of the overall reaction depends on the rate at which reactants are consumed or the rate at which the products are formed. If a graph is plotted between the concentration of reactants an
Average and Instantaneous Rate
The rate of reaction can be classified into average and instantaneous rates depending on the amount of time period. If the time period taken is finite, then it’s called the average rate and is represented as, Δl → change in concentration Δt → change in time r avg → average rate The average rate doesn’t give exact information in most cases about the
