A Catalyst is Specific in its Action

A catalyst is specific in its action. All material bodies cannot act as catalysts in all reactions. A suitable catalyst for a particular reaction is to…
Why a Catalyst cannot Start a Reaction?
Chemistry

Why a Catalyst cannot Start a Reaction?

A catalyst cannot, in general, start a reaction. Some reactions, however, cannot start in absence of the catalyst. An example is the reaction between H2 (g)…
Differences between Homogeneous Catalysis and Heterogeneous Catalysis
Chemistry

Differences between Homogeneous Catalysis and Heterogeneous Catalysis

Homogeneous catalysis takes place when the catalyst and the other reactants are all dissolved in the same solution. Heterogeneous catalysis typically involves the use of…

Homogeneous Catalysis

Homogeneous catalysis In a reaction, if the catalyst is present in the same phase as the reactants, it is called a homogeneous catalyst and the…
