For the formation of hydrogen iodide, H2(g) + 12(g) - 2HI(g) the value of the equilibrium constant at 700K is 54.7. If one mole of H2 and one mole of 12 are the
only materials initially present, what will be the equilibrium concentrations of H2,
12, and HI.

t 700 K, the equilibrium constant for the reaction;

H  

2(g)

​  

+I  

2(g)

​  

⇌2HI  

(g)

​  

 is 54.8.

If 0.5 mol litre  

−1

 of HI  

(g)

​  

 is present at equilibrium at 700 K, what are the concentrations of H  

2(g)

​  

 and I  

2(g)

​  

 assuming that we initially started with HI  

(g)

​  

 and allowed it to reach equilibrium at 700 K.

wher is the rest of the question

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.
