Consider the following elementary reaction:
N2O—> N2 + O
suppose we let K1 stand for the rate constant of this reaction, and k-1 stand for the rate constant of the reverse reaction. write an expression that gives the equilibrium concentration of N2O in terms of k1, k-1 and the equilibrium concentrations of N2 and O

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:

Explanation :

As we are given that:

The rate of reaction in forward direction =

The rate of reaction in backward direction =

As we know that at equilibrium, rate of forward reaction is equal to the rate of backward reaction.

So,

The expression that gives the equilibrium concentration of N₂O in terms of K₁, K⁻¹ and the equilibrium concentrations of N₂ and O₂ is:
