A100 ml reaction vessel initially contains 2.60×10^-2 moles of no and 1.30×10^-2 moles of h2. at equilibrium the concentration of no in the vessel is 0.161m. at equilibrium the vessel also contains n2, h2o, and h2. what is the value of the equilibrium constant for kc for the following reaction?
2h2 (g) + 2no(g) < —> 2h2o (g) + n2 (g)

Explanation:

The volume of vessel used= ml

Initial moles of NO= moles

Initial moles of H2= moles

Concentration of NO at equilibrium= M

Moles of NO at equilibrium=

                                            = moles

                    2H2 (g)        +    2NO(g) <—>    2H2O (g) +    N2 (g)

Initial          :1.3*10^-2          2.6*10^-2                0                   0        moles

Equilibrium:1.3*10^-2 - x     2.6*10^-2-x              x                   x/2     moles

∴

⇒

Equilibrium:0.31*10^-2      1.61*10^-2          0.99*10^-2        0.495*10^-2  moles

⇒

⇒

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.
