Chemical Reaction Engineering The increase in the rate of reaction with temperature is due to Increase in the average kinetic energy of the reacting molecules Decrease in activation energy None of these Increase in the number of effective collisions Increase in the average kinetic energy of the reacting molecules Decrease in activation energy None of these Increase in the number of effective collisions ANSWER DOWNLOAD EXAMIANS APP
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
