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