Experiments have shown that the equilibrium constant Kp for the reaction NO(g) + NO2(g) ⇌ N2O3(g) is 0.03. A chamber with a cons
zepelin [54]

Answer:

The reaction will shift to the right

Explanation:

In the reaction:

NO(g) + NO₂(g) ⇌ N₂O₃(g)

Kp of reaction is:

kP = \frac{P_{N_2O_3} }{P_{NO}P_{NO_{2}}} = 0.03

<em>Where P represents the pressures in equilibrium</em>

Replacing in the kP formula the initial pressures:

\frac{50MPa}{200MPa*250MPa} = 0.001

As the <em>Reaction quotient (Q) </em>is less than kP, <em>the reaction will shift to the right </em>producing more N₂O₃ until Q = kP.
