Answer : The concentration of at equilibrium is 0 M.
Solution : Given,
Concentration of = 0.0200 M
Concentration of = 1.00 M
The given equilibrium reaction is,
Initially conc. 0.02 1.00 0
At eqm. (0.02-x) (1.00-3x) x
The expression of will be,
By solving the term, we get:
Concentration of at equilibrium = 0.02 - x = 0.02 - 0.02 = 0 M
Therefore, the concentration of at equilibrium is 0 M.
Answer:
The temperature of the air at this given elevation will be 53.32425°C
Explanation:
We can calculate the final temperature through the combined gas law. Therefore we will need to know 1 ) The initial volume, 2 ) The initial temperature, 3 ) Initial Pressure, 4 ) Final Volume, 5 ) Final Pressure.
Initial Volume = 1.2 L ; Initial Temperature = 25°C = 298.15 K ; Initial pressure = 1.0 atm ; Final Volume = 1.8 L ; Final pressure = 0.73 atm
We have all the information we need. Now let us substitute into the following formula, and solve for the final temperature ( T ),

298.15 / 1
1.2 ) K = 326.47425 K,
T = 326.47425 K = 53.32425 C
