The rate law for a reaction is determined by:

A.Experimental measurement of reaction rates
B.The enthalpy of the reaction
C.The stoichiometric coefficients of the balanced equation
D.The equilibrium constant

Explanation

Core Concept

Rate laws must be determined experimentally because the stoichiometric coefficients do not necessarily correspond to the reaction orders. Only for elementary steps do coefficients equal orders.

Correct Answer

AExperimental measurement of reaction rates
