In which of the following reactions would you expect the orientation factor to be least important in leading to reaction: co+o→co2 or h+f→hf? match the words in the left column to the appropriate blanks in the sentence on the right. co+o→co2c o + o rightarrow c o subscript2 termolecular unimolecular monatomic diatomic h+f→hfh + f rightarrow h f the orientation factor is less important in the orientation factor is less important in blank because the reactants are blank and spherical (nondirectional); all collision orientations are equally effective. because the reactants are the orientation factor is less important in blank because the reactants are blank and spherical (nondirectional); all collision orientations are equally effective. and spherical (nondirectional); all collision orientations are equally effective.
