FACTORS EFFECTING RATE OF REACTIONS
Concentration-As the concentration of reactants increases, the no of effective collisions
increases, then the rate of reaction increases
Temperature-As the Temperature increases. Kinetic energy of the molecule increases, then the rate of
reaction increases
Nature of reactants
Surface area-As the Surface area increases then the rate of reaction increases
Pressure-As pressure increases the molecule comes closer. The effective collisions increases,
then the rate of reaction increases
Catalyst-Positive catalyst: Catalyst that increase the rate of reaction.
Negative catalyst: Catalyst that decrease the rate of reaction.
Forward reaction-Reactants turn into products is known as forward reaction. Backward reaction-Products turn into reactants is known as backward reaction.
Reversible reactions-Reactions taking place in both directions
Chemical Equilibrium is the point at which the rate of the forward reaction becomes equal to
the rate of the backward reaction in a chemical reaction.
