Which of the reaction shown is most likely to be an elementary step? CH4 + 202...
Can an intermediate appear in the net balanced reaction? Yes, because it is part of the reaction mechanism No, because it is a product in one step but a reactant in another step and cancels out of the net reaction Oo oo Yes, because all species in the reaction must show up in the net reaction No, because it is a product and products do not appear in the rate law For a certain reaction the rate law is: Rate...
