Chemical Reaction Engineering The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Value of threshold energy decreases Collision frequency increases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Value of threshold energy decreases Collision frequency increases ANSWER DOWNLOAD EXAMIANS APP
