Chapter 10, Problem 90E

The equilibrium constant K for the reaction
$\text{2Cl(}g\text{)}\rightleftharpoons {\text{Cl}}_{\text{2}}\text{(}g\text{)}$
was measured as a function of temperature (in kelvins).A graph of ln(K) versus 1/T for this reaction gives astraight line with a slope of $1.352\times {10}^4\text{K}$ and a y interceptof 214.51. Determine the values of $\Delta H°$ and $\Delta S°$ for this reaction. (See Exercise 88.)
