A simple method for the laboratory preparation of hydrogen involves reaction of zinc with hydrochloric acid
Zn(s) + 2 HCl(aq) ® ZnCl2(aq) + H2(g) DH = -152.5 kJ

Explain how much heat in kilojoules are evolved if a total of 968.4mL of H2 was collected over water at 14.00°C as well as an atmospheric pressure of 557.04 mm Hg. The partial pressure of water at this temperature is11.99 mm Hg? Presume heat evolved is directly proportional to the moles produced.
