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 Value of threshold energy decreases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Collision frequency increases Value of threshold energy decreases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy ANSWER DOWNLOAD EXAMIANS APP
