Chapter 6, Problem 28P(choose chapter or problem)
Consider the reaction
\(\mathrm{H}_{2}(g)+\mathrm{Cl}_{2}(g) \rightarrow 2 \mathrm{HCl}(g)\)
\(\Delta H=-184.6 \mathrm{~kJ} / \mathrm{mol}\)
If 3 moles of \(\mathrm{H}_{2}\) react with 3 moles of \(\mathrm{Cl}_{2}\) to form HCI, calculate the work done (in joules) against a pressure of 1.0 atm at \(25^{\circ} \mathrm{C}\). What is \(\Delta U\) for this reaction? Assume the reaction goes to completion.
