Question

which factor can decrease the rate of a chemical reaction? low activation energy high pressure low temperature high concentration of enzyme

Explanation:

• Low activation energy: Facilitates reaction, increasing rate.
• High pressure (for gas - phase reactions): Increases collision frequency, increasing rate.
• Low temperature: Decreases molecular kinetic energy, reducing collision frequency and effective collisions, thus decreasing reaction rate.
• High enzyme concentration (for enzyme - catalyzed reactions): Increases reaction rate.

Answer:

low temperature
