Now the second step is the following. This intermediate or this intermediate reacts with 1 mol reactants to produce again one molar hydroxide and one of our products. Now notice that this is one of our products. So step two is responsible for producing this product, namely this guy. And now these two guys, two moles of hydroxide finally react with two moles of hydronium to produce our four moles of water, the second product. So the second step is responsible for producing one of the products while the third step is responsible for producing the second type of product.
