Question

What is the reaction when upper n a subscript 2 upper c upper o subscript 3 reacts with upper k?

1) No reaction
2) K₂CO₃
3) NaK
4) CO₃

Answer 1

There will be no reaction between Na2CO3 and K; they are both cations and cannot form a compound together. The correct answer is (1) No reaction.

Step-by-step explanation:

When Na2CO3 reacts with K (potassium), the reaction does not proceed since both are cations and cannot directly form a compound. Therefore, the correct answer from the provided options is (1) No reaction.

Regarding the rate law information provided, explaining the reaction rate for a different reaction involving NO2 and CO: The rate law for this reaction is given as rate = k[NO2] [CO]. The reaction is considered second order in NO2, (m = 2), and zero order in CO, (n = 0), which results in a rate law of rate = k[NO2]^2[CO]^0 = k[NO2]^2. As any number raised to the zero power equals one, the concentration of CO can be omitted from the rate law, meaning the rate is solely dependent on the concentration of NO2.
