Suppose a 500.mL flask is filled with 0.40mol of N2 and 1.0mol of NO. The following reaction becomes possible: N2g+O2g ->2NOg
The equilibrium constant K for this reaction is 5.93 at the temperature of the flask. Calculate the equilibrium molarity of N2. Round your answer to two decimal places.

[N₂] = 1.1M

Explanation:

Based on the chemical reaction:

N₂(g) + O₂(g) ⇄ 2 NO(g)

Equilibrium constant, K, is defined as:

K = 5.93 = [NO]² / [N₂] [O₂]

Where [] are equilibrium concentrations of each specie

As initial concentrations are:

N₂ = 0.40mol / 0.500L = 0.8M

NO = 1mol / 0.500L = 2M

The equilbrium concentrations are:

[NO] = 2M - 2X

[N₂] = 0.8M +X

[O₂] = X

Replacing:

5.93 = [2 - 2X]² / [0.8+X] [X]

5.93 = 4 - 8X + 4X² / 0.8X + X²

4.744X + 5.93X² = 4 - 8X + 4X²

1.93X² + 12.744X - 4 = 0

Solving for X:

X = -6.9M → False solution. There are no negative concentrations

X = 0.3M. Real solution.

[N₂] in equilibrium is:

[N₂] = 0.8M +0.3M

[N₂] = 1.1M

Explanation:

The novel Snow Flower and the secret fan is written by Lisa See which had taken place in China in 1800s . Lisa See had written about the girl’s life in China when girls were having their feet bound and then they used to spend the rest of their lives in isolation with only one window through which they can see . They were kept un educated and isolated . They were not projected to think or to be artistic and to have emotions . But in one distant country girls and women had established their own secret code which is called “Nu Shu” which means women writing . This “nushu” is the one gender based language to be written or one written language which had been found by these women of China in the world . Some girls were being paired as “old-sames” in the arousing matches that had lasted all the way through their lives .They used to paint many letters on fans side by side embellished messages on handkerchiefs and also composed stories an that way reaching out of their windows for sharing their dreams expectations , hopes ,accomplishments and success. In this novel an old woman used to tell her own relationship with her “old-same” along with their marriages which were arranged and the happiness and tragedies of motherhood awaiting a horrible misinterpretation which are written on their secrets fan will make a threat to rip them apart. Through the features and emotional quality of Memoirs of a Geisha ,this novel had delved into one of the most mysterious and precious relationships of all time friendship of females. As of foot-binding onwards the girls and women used to live isolated in a second-story compartment of their house hold because of the difference between the inner monarchy of the house and the outer monarchy of men set at the very heart of Confucian society. This novel depicts the sufferings of humans in a lot of ways, like the psychological pain of foot binding , the pain of women of that time who were being treated as a property that time and the horrible and painful return back down the mountain trail with dead bodies at every place.
