In the lab you are comparing two reactions, Reaction A and Reaction B. You find that Reaction A needs an initial input of energy to get it started while Reaction B appears to start on its own. Which reaction will go to completion (all reactants will be converted into products)? I. Reaction A II. Reaction B III. We cannot tell from the information given. Because IV. Reactions that go to completion have lower activation energies. V. With initial input of energy all of the reactants convert into products. VI. The position of equilibrium is not related to the rate of reaction.
