Catalysts alter reaction rates by 

Ethane of volume 400 cm\(^3\) was completely burnt in excess oxygen according to the following equation:

2C\(_2\)H\(_6\)\(_(g)\)   +  7O\(_2\)\(_(g)\) → 6H\(_2\)O\(_(g)\) + 4CO\(_2\)\(_(g)\)

Calculate the volume of steam that would be produced.

A saturated solution at 30\(^0\)C will normally produce crystals at a temperature of

The following organic compounds are polymers except

According to the collision theory of reaction rates, which of the following conditions is not required for two molecules to react? The molecules must
