Which statement describes a homogeneous catalyst? it is in a gaseous phase only. it is in the same phase as the reactants. it is completely consumed by reactants. it forms different products than the uncatalyzed reaction forms.

Catalyst are those compounds or elements which doesn't take part in the chemical reactions but only enhances the rate of the reaction i.e. it can either increase or decrease the rate of the reaction.

There are two forms of catalyst, when the phase of the catalyst is same as that of the reactants, then it is said to be a homogeneous catalyst whereas when the phase of the catalyst is different as that of the reactants, then it is said to be a heterogeneous catalyst.

Hence, homogeneous catalyst is defined as the catalyst in which catalyst is present in same phase as that of the reactants i.e. second option is the correct answer.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
