The rate at which a chemical reaction occurs is dependent on many factors. Which of the following will increase the rate of reaction?
Loading ...
Correct Answer: B. Adding a catalyst.
The rate at which a chemical reaction occurs is increased by increasing the temperature, adding a catalyst, increasing the concentration of a reactant in solution, increasing the partial pressure of a reactant gas and increasing the surface area of a reactant solid.
Catalysts increase the rate of reaction by providing an alternative way for the reaction to continue with a lower activation energy, thus making the reaction easy to occur under any given conditions.
