CORRECTLY EXPLAIN How will the equilibrium shift if the following changes are made? State if the reaction will shift to the left or right and explain why it will shift in that direction.
PCl5 (g)+heat ⇌ PCl3 (g)+ Cl2 (g)
1) Temperature is increased
2) Pressure is increased
3) Cl2 is added
4) PCl3 is removed as it is formed

c. orbital shape i hope this is correct

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.
