Three questions with two multiple choice answers-- please help!
1. Study the chemical reaction.
A ⟶ B + C
This reaction is second order in A.
What is the rate law for this reaction?
> Rate = K [B][C]^2
> Rate = K [A]^2
2. Study the reaction.
NH4+ + NO2– ⟶ N2 + 2H2O
The rate of this reaction is proportional to the concentration of ammonium (NH4+) and the concentration of nitrogen dioxide (NO2–).
What is the rate law of this reaction?
> Rate = K[NH4+][NO2–]
> Rate = K[N2][H2O]^2
3. Study the reaction and read the statement.
+32→6
The rate constant for this reaction is 0.025, and the reaction is second order in Xe and first order in F2.
What is the rate of the reaction if [Xe] is 0.25 M, and [F2] is 0.4 M?
> 6.3 × 10^–4
> 2.5 × 10^–3
