- Which of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas. Overview of the experiment:Diagrams like the one below are used to represent exothermic reactions. For instance, consider burning charcoal (which almost entirely pure element carbon). A=carbon and B=oxygen, when they react they form C=carbon dioxide. A little chemistry vocab: does substance C in the diagram represent a reactant or the product?
