Which factor can decrease the rate of a chemical reaction?
A. low activation energy
B. high pressure
C. low temperature
D. high concentration of enzyme

The factor that can decrease the rate of a chemical reaction is low temperature, as it reduces the kinetic energy of molecules, resulting in fewer successful collisions. In contrast, factors like high pressure, low activation energy, and high concentration of enzymes generally increase reaction rates. Therefore, the correct choice is C. low temperature.
