Explain the factors affecting rate of a reaction.

Explanation

(i) Concentration of Reactants : When the concentrations of the reactants are raised, the reaction proceeds more quickly.
(ii) Temperature of System : Raising the reaction temperature by `10^(@)C` can double or triple the reaction rate.
(iii) Nature of Reactant : When solids and liquids react, increasing the surface are of the solid will increase the reaction rate.
(iv) Presence of Catalyst: Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.
(v) Surface Area : Increasing the surface area of the solid will expose more solid molecules to the liquid, which allows for a faster reaction.
