If the reaction CH4(g) O2(g) <--> CO2(g) 2H2O(g) is in equilibrium, what is the effect of adding a catalyst

Adding a catalyst increases the speed of the reaction.

Explanation:

The catalyst increases the reaction rate since what it does is to consume the reagents more easily in order to obtain the products faster.

The catalysts DO NOT ALTER THE QUANTITY OF PRODUCTS OR REAGENTS, that is to say that they do not add grams nor do they intervene in the masses of the chemical compounds of the reaction, they only speed up the procedure.

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.
