Unformatted text preview: factor than more frequent collisions). • Increasing the surface area of solids reactants: This increases the number of particles
that can collide, i.e., increases the frequency of successful collisions. • Catalysts: Lower the activation energy of reaction by providing an alternate pathway
and thus increase the rate of reaction. Catalysts are specific to reactions and are used in
o Homogeneous catalysis: Where the catalyst is in the same phase as the
reactants, e.g., esterification reaction to produce sweet smelling compounds
for perfumes, and in the food industry. o Heterogeneous catalysis: Where the catalyst and reactants are in different
phases e.g., in the manufacture of ammonia, sulfuric acid, hydrogenation of
alkenes etc. o A catalyst does not change the position of equilibrium; rather it increases the
rate of both the forward and reverse reactions t...
