Which will increase the rate of a chemical reaction?
A. Adding a positive catalyst.
B. Decreasing the pressure.
C. Decreasing the temperature.
D. Adding a negative catalyst.

Respuesta :

Adding a positive catalyst will increase the rate of chemical reaction.

Step-by Step-Explanation:

  • Catalyst is a substance that can change the rate of a chemical reaction but the catalyst itself does not undergo any change.
  • Depending on the type of change it brings in rate of reaction, catalysr is classified as: Positive Catalyst and Negative Catalyst.
  • Catalyst that increases the rate of reaction is a positive catalyst.
  • Catalyst that decreases the rate of reaction is a negative catalyst.
