For the elementary reaction NO3 + CO → NO2 + CO2 the molecularity of the reaction is ________, and the rate law is rate = ______
blagie [28]

Answer: For the elementary reaction NO_3+CO\rightarrow NO_2+CO_2 the molecularity of the reaction is 2, and the rate law is rate = k[NO_3]^1[CO]^1

Explanation:

Order of the reaction is defined as the sum of the concentration of terms on which the rate of the reaction actually depends. It is the sum of the exponents of the molar concentration in the rate law expression.

Elementary reactions are defined as the reactions for which the order of the reaction is same as its molecularity and order with respect to each reactant is equal to its stoichiometric coefficient as represented in the balanced chemical reaction.

Molecularity of the reaction is defined as the number of atoms, ions or molecules that must colloid with one another simultaneously so as to result into a chemical reaction.  Thus it can never be fractional.

For elementary reaction NO_3+CO\rightarrow NO_2+CO_2 , molecularity is 2 and rate law is rate=k[NO_3]^1[CO]^1
