Question

B. Nitrous Oxide (N_{2}*O) commonly known as laughing gas, is easily oxidized to dinitrogen tetraoxide (N_{2}*O_{4}) . If the equilibrium concentrations of f N 2 O? , O_{2} and f*N_{2}*O_{4} are 0.089M, 0.064M, and 2.5M, respectively, what is the equilibrium constant k_{c} for the reaction?

2N 2 O (g) +3O 2(g) Leftrightarrow2N 2 O 4 8)

Answer 1

Solution:

Balanced chemical equation:

2N₂O(g) + 3O₂(g) → 2N₂O₄(g)

The equilibrium constant (K_c) expression for the reaction:

[N₂O₄] = 2.5 M

[N₂O] = 0.089 M

[O₂] = 0.064 M

Therefore,

Answer: The equilibrium constant (K_c) for the reaction is 3.0×10⁶
