Question 8 • 26-27 - C - RUSD Chemistry in the Earth System

Which statement best describes why rate laws are important?

Answer
A
to see if a chemical reaction can actually take place
B
to determine what products are formed in a chemical reaction
C
to determine how fast a chemical reaction will take place
D
to see how much heat energy a chemical reaction releases

Explanation

A rate law relates the concentrations of reactants to the reaction rate. It is used to determine how fast a chemical reaction will take place, rather than the heat released, whether it can occur, or which products form. Therefore, the best choice is “to determine how fast a chemical reaction will take place.”
