Catalysis

Catalysis

The substance in its small quantity increases or decreases or inhibit the rate of reaction without any change in mass or compositions is called catalyst.

There are two types of catalysis

1.       Homogeneous catalysis

Ch3cho(g) __I2(g) Catalyst__>ch4(G) +co (g)

In homogeneous catalysis both reactant and catalysis are same phase is called Homogeneous catalysis.

In this above reaction  formation of  methane from acetaldehyde  in the presence of iodine catalyst these are same phases.

2.Heterogeneous catalysis.

 In the heterogeneous catalysis and reactants are different phases

N2(g) + 3H2(g) ____Fe(S) > 2NH3(g)

In this  above reaction formation of ammonia from hydrogen and nitrogen where both reactant and catalysis are different phases.
