Question

Nitric oxide, an important pollutant in air, is formed from the elements nitrogen and oxygen at high temperatures, such as those obtained when gasoline burns in an automobile engine. At 2000°C, K for the reaction N2(g) + O2(g) 2NO(g) is 0.01. Predict the direction in which the system will move to reach equilibrium at 2000°C if 0.4 moles of N 2, 0.1 moles of O 2, and 0.08 moles of NO are placed in a 1.0-liter container.

Answer 1

The Equilibrium will shift towards the left.

Step-by-step explanation:

The reaction for the formation of nitric oxide is follows,

`N_2(g)+O_2(g)\leftrightarrow2NO(g)`

Expression for reaction quotient is as follows,

`Q=([NO]^2)/([N_2][O_2])`

Putting the values according to the data given and calculating reaction quotient for the reaction

`Q=0.16`

So, the reaction quotient is 0.16.

and the value of K is 0.01 .

Q>K

Since the value of K is less than Q, therefore the reaction will shift towards left.
