Instanton reaction rate constants (and Eckart corrected rate constants in the case of C₂H₄ + OH → C₂H₄OH) in the [500, T_min] range, with T_min being the lowest temperature achieved in our calculations for each particular addition reaction starting from C₂H₄. The vertical line represents the crossover temperature, T_c.
