Collision Theory of Chemical Reactions
According to this theory, the reactant molecules are assumed to be hard spheres and reaction is postulated to occur when molecules collide with each...
Effect of Catalyst on Rate of Reaction
Effect of Catalyst on Rate of Reaction
A catalyst is a substance which alters the rate of a reaction without itself undergoing any permanent chemical...
Arrhenius equation
Arrhenius equation
Quantitively, the temperature dependence of the rate of a chemical reaction can be explained by Arrhenius equation
where A is the Arrhenius factor or...
Temperature Dependency of a Rate of Reaction
Temperature Dependency of a Rate of Reaction
Activation Energy
According to collision theory, a reaction takes place because the reactant molecules collide with each other.
The minimum...
Half-Life of a Reaction
Half-Life of a Reaction
The half-life of a reaction is the time in which the concentration of a reactant is reduced to one half of...
Integrated Rate Equations
Integrated Rate Equations
The integrated rate equations are different for the reactions of different reaction orders. We shall determine these equations only for zero and...
Molecularity of a Reaction
Molecularity of a Reaction
The number of reacting species (atoms, ions or molecules) taking part in an elementary reaction, which must collide simultaneously in order...
Rate Expression and Rate Constant
Rate expression and rate constant
Consider a general reaction
aA + bB → cC + dD

Chemical kinetics & Rate of Reaction
What is Chemical kinetics?
Chemical kinetics is the branch of chemistry which deals with the study of rates (or fastness) of chemical reactions, the factors...
