Answer:
Rate = K[NH₄⁺][NO₂⁻]
Explanation:
In kinetics studies of reaction, rate law is a mathematical expression that relates speed of reaction with concentrations of the reactants. For a reaction:
aA + nN → cC + dD
The rate law is expressed in terms of [A] and [B] as follows:
Rate = K[A]ᵃ[N]ⁿ
Where K is rate constant.
For the reaction:
NH4+ + NO2– ⟶ N2 + 2H2O
The rate law is:
Rate = K[NH₄⁺][NO₂⁻]
As was said in the problem, the rate is porportional to [NH₄⁺] and to [NO₂⁻]
