ch 14 answer each of these.
answer all 3 please
HI HCI reactants Reaction intermediates are species that are formed in one step of a mechanism and consumed in another step. For example, can act as an intermediate in the following reaction: H2(g) + 2Cl(g) + 2HCl(g) + 12(g). You can often express the concentration of in terms of the concentrations of the of the overall reaction to be consistent with the experimentally observed rate law as the overall reaction...
