Chemical Reaction Engineering The minimum energy required to allow a chemical reaction to proceed is termed as the 'threshold energy '. Chemical reaction with low activation energy are Highly temperature sensitive Always irreversible Insensitive to temperature changes Mostly irreversible Highly temperature sensitive Always irreversible Insensitive to temperature changes Mostly irreversible 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 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 ANSWER DOWNLOAD EXAMIANS APP
