Which of the following is NOT an example of a topic studied in chemical kinetics?
A
Investigating how temperature affects reaction speed
B
Determining the rate at which hydrogen peroxide decomposes
C
Studying the effect of a catalyst on reaction rate
D
Calculating the equilibrium constant for a reversible reaction
Verified step by step guidance1
Understand that chemical kinetics is the study of the rates of chemical reactions and the factors that affect these rates.
Identify that topics like how temperature affects reaction speed, the rate of hydrogen peroxide decomposition, and the effect of catalysts on reaction rates all involve studying reaction rates and mechanisms, which are core to chemical kinetics.
Recognize that calculating the equilibrium constant for a reversible reaction is related to chemical equilibrium, which deals with the position of balance between reactants and products, not the speed of the reaction.
Distinguish between chemical kinetics (reaction rates and mechanisms) and chemical equilibrium (concentrations of species at equilibrium and thermodynamics).
Conclude that calculating the equilibrium constant is NOT a topic studied in chemical kinetics, making it the correct answer to the question.
