1. The same reaction 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) ...
