The rate law for a reaction is determined by:
A.The stoichiometric coefficients of the balanced equation
B.Experimental measurement of reaction rates
C.The equilibrium constant
D.The enthalpy of the reaction
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
BExperimental measurement of reaction rates
