A certain decomposition reaction has a half-life that depends on the initial concentration of the reactant, and its rate is observed to slow down as the reaction proceeds. Identify which statement is most likely correct for this reaction and explain why the other statements are incorrect. O2(g) + 2 NO(g) → 2 NO2(g) (i)The half-life of the reaction increases as the initial concentration increases. (ii)A doubling of the initial concentration of the reactant results in a quadrupling of the rate. (iii)A plot of the natural log of the concentration of the reactant as a function of time is linear.

Question

A certain decomposition reaction has a half-life that depends on the initial concentration of the reactant, and its rate is observed to slow down as the reaction proceeds. Identify which statement is most likely correct for this reaction and explain why the other statements are incorrect.

O2(g) + 2 NO(g) → 2 NO2(g)

(i)The half-life of the reaction increases as the initial concentration increases.

(ii)A doubling of the initial concentration of the reactant results in a quadrupling of the rate.

(iii)A plot of the natural log of the concentration of the reactant as a function of time is linear.
