Chemical Kinetics – Detailed Notes (Class 11)
Introduction
1 Chemical kinetics studies the rate of chemical reactions.
2 It helps understand how fast or slow a reaction occurs.
Rate of Reaction
1 Rate = Change in concentration / Time
2 It decreases with time as reactants are used up.
Factors Affecting Rate
1 Concentration: More particles → more collisions
2 Temperature: Higher temperature → more energy
3 Catalyst: Provides alternate path
4 Surface Area: More exposed area increases rate
Rate Law
1 Rate = k[A]^m[B]^n
2 k is rate constant
3 m and n are orders determined experimentally
