Question

The reaction of nitrogen dioxide with carbon monoxideNO2 + CO→ NO + CO2is second order in NO2 and zero order in CO.Complete the rate law for this reaction . Use the form k[A]m[B]n... , where '1' is understood for m, n ...(don't enter 1) and concentrations taken to the zero power do not appear.

Answer 1

Answer:

r = k.[NO₂]²

Explanation:

Let's consider the following reaction.

NO₂ + CO → NO + CO₂

A generic rate law is:

r = k.[A]ᵃ.[B]ᵇ

where,

r is the reaction rate

k is the rate constant

[A] and [B] are the molar concentrations of the reactants

a and b are the reaction orders with respect to A and B, respectively

The reaction is second order in NO₂ and zero order in CO. The corresponding rate law is:

r = k.[NO₂]².[CO]⁰

r = k.[NO₂]²
