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
Chemical Reaction Engineering If the rate of a chemical reaction becomes slower at a given temperature, then the Entropy changes Initial concentration of the reactants remains constant Free energy of activation is higher Free energy of activation is lower Entropy changes Initial concentration of the reactants remains constant Free energy of activation is higher Free energy of activation is lower ANSWER DOWNLOAD EXAMIANS APP
