Question

exam content page 1 of 5 question 1 how is a rate law determined? a using the coefficients from the balanced equation b using experimental data c using a reaction - energy diagram d using logic

Explanation:

The rate law of a chemical reaction is an experimentally - determined relationship. It cannot be simply derived from the coefficients of a balanced equation (this is only true for elementary reactions in some cases), nor from a reaction - energy diagram or just logic. Experimental data such as measuring the initial rates of a reaction while varying the concentrations of reactants is used to determine the rate law.

Answer:

B. using experimental data
