Answer : The expression that gives the equilibrium concentration of N₂O in terms of K₁, K⁻¹ and the equilibrium concentrations of N₂ and O₂ is:
[tex][N_2O]=\frac{K^{-1}}{K_1}\times [N_2][O_2][/tex]
Explanation :
As we are given that:
The rate of reaction in forward direction = [tex]R_f=K_1\times [N_2O][/tex]
The rate of reaction in backward direction = [tex]R_b=K^{-1}\times [N_2][O_2][/tex]
As we know that at equilibrium, rate of forward reaction is equal to the rate of backward reaction.
So,
[tex]R_f=R_b[/tex]
[tex]K_1\times [N_2O]=K^{-1}\times [N_2][O_2][/tex]
The expression that gives the equilibrium concentration of N₂O in terms of K₁, K⁻¹ and the equilibrium concentrations of N₂ and O₂ is:
[tex][N_2O]=\frac{K^{-1}}{K_1}\times [N_2][O_2][/tex]
