Which statement below concerning elementary processes (or
steps), the mechanism of a reaction and the overall reaction is
correct?
The overall rate law derived from the mechanism must agree with
the observed rate law for the overall reaction.
The rate law for an elementary process can be predicted from
the chemical equation for that process.

The rate of a chemical reaction can be measured as the rate of appearance of any of the products or as the rate of disappearance of any of the reactants. These relative rates of reaction are related through the stoichiometry of the overall reaction. For example, the rate of the reaction shown below can be determined by measuring the initial rate of disappearance of I, -A[I/At. Cl03-(aq) + 91. (aq)+ 6 H+ (aq) → 31.3 (aq) + Cl-(aq) + 3H20...
