Chapter 17, Problem 97CWP

Given the thermodynamic data below, calculate ∆S and ∆S_surr for the following reaction at 25°C and 1 atm:

${\text{XeF}}_{\text{6}}\left(g\right)\to {\text{XeF}}_{\text{4}}\left(s\right)+{\text{F}}_{\text{2}}\left(g\right)$

	$\Delta H_{\text{f}}^{\text{o}}$(KJ/mol)	S°(J/K mol)
XeF6(g)	-294	300.
XeF4(s)	-251	146
F2(g)	0	203
