The same reaction (HCl(aq) + NaOH(aq) -> NaCl(aq) + H2O(l))
takes place in two different vessels, which are initially at atmospheric pressure (1 atm). The first vessel is rigid and does not expand with change in pressure; the second vessel will expand to maintain a pressure of 1 atm inside. Over the course of a reaction, the second vessel expands by 1 liter.
a) What is the amount of PV work done by the reaction for each of the vessels?
b) Which vessel's content has a higher enthalpy?
c) Based on the answer to part b, which vessel would you expect to have a higher temperature?
More information: 1 liter of 1 M NaOH and 1 liter of 1 M HCl. The initial temperature of the two solutions is 25°C. The specific heat of water is 4.184 J/g°C.
