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