Amongst the following chemical reactions, the one representing homogeneous catalysis is 

Platinised asbestos helps in the formation of $$SO_{3}$$, from $$SO_{2}$$ and $$O_{2}$$. But, if even a small amount of $$As_{2}O_{3}$$ acts here as

A catalyst is substance which

The decomposition of hydrogen peroxide can be slowed by the addition of a small amount of acetamide. The latter acts as a 

Catalyst used in hydrogenation of oils is

Addition of catalyst in a system

In the titration between oxalic acid and acidified potassium permanganate, the manganous salt formed catalyzes the reaction. The manganous salt is

Platinized asbestos is used as a catalyst in the manufacture of $$H_{2}SO_{4}$$. It is an example of 

The example of heteropolar sol is:

In Bredig's arc method some alkali is added because_____
