4) Clouds usually form when O A) air temperature reaches the dewpoint
B) evaporation has warmed the surrounding air
C) relative humidity is 0%
D) condensation nuclei have been removed from the air

The activation energy for this reaction is 75 kj·mol–1. the enzyme catalase (found in blood) lowers the activation energy to 8.0 kj·mol–1. at what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°c?
