Answer to Question #100739 in General Chemistry for Lithia

Question

Calculate delta h delta s delta g and t of the reaction s+o2=so2

Answer 1

$∆H=H(so2)- H (s+o2)$

∆H=296.81-(36.36+48) =212.45 J/mol

$∆S= S(products)- S(reactants)$

∆S= S(so2) -S(s+o2)=248.21-( 32.054+205.0) =11.156 J/K.mol

$∆G=∆H- T*∆S$

∆G=212.45- 273.15*11.156 = -2834.81J/mol
