For the conversion of diamond to graphite, C(diamond) - C(graphite), the standard free energy change
(AGrxn) is-2.90 kJ/mol.
This reaction is
spontaneous
Based on this e nonspontaneous. Ineous reactions always proceed under all conditions?

sure what is it? ^w^

i think its 100.

hope this !

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.
