Which substance controls rate of reaction in method of large excess?
Correct answer: C. Substance in small amount
- A. Substance in excess
- B. Catalyst
- C. Substance in small amount
- D. Quantity of product
Explanation

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
