Comments | the lower mass isotope is faster. this is the primary kinetic isotope effect. results from the effective mass for the higher isotope bein larger and thus the lowest energy being lower which then requires higher activation energy for bond cleavage. Tritium reacts 60 times more slowly. refers to room temperature |
