Overview

Chemical kinetics is the branch of chemistry that deals with reaction rates and reaction mechanisms. It explains how fast a reaction occurs, why some reactions are instantaneous while others are slow, and how concentration, temperature, and catalysts change the rate. Thermodynamics tells whether a r

Key Concepts

Rate of reaction is the change

Rate of reaction is the change in concentration of a reactant or product in unit time. It can be written as rate of disappearance of a reactant or rat

Average rate is measured over

Average rate is measured over a time interval and uses total change in concentration divided by time taken. Instantaneous rate is the rate at a partic

Rate law is the expression

Rate law is the expression that relates reaction rate to the molar concentrations of reactants raised to powers determined experimentally. The rate co

The order of a reaction

The order of a reaction is the sum of the powers of concentration terms in the rate law. It may be zero, fractional, or an integer. It is an experimen

Molecularity is the number of reacting

Molecularity is the number of reacting species that collide simultaneously in an elementary reaction. It can never be zero or fractional and has meani

Learning Objectives

  • Define average rate and instantaneous rate of a reaction
  • Express reaction rate in terms of change in concentration or partial pressure
  • Differentiate between elementary and complex reactions
