You are provided withthe followingDeltaG^(@)values:S_ 8+2 O _2to2 SO_2 , DeltaG^(@)at 1073K=-544 kJ2Zn+ S_2 to2ZnS , Delta G^(@)at1073K= -293kJ2Zn + O _2 to2 ZnO ,DeltaG^(@)at1073K =-480kJCalculateDeltaG^(@)at1073 K forthefollowingreaction at thisremperature, 2ZnS +3O _2to2 ZnO+2 SO _2andpredictwhether thisreactionis thermodynamically feasibleor not.

Answer»

Solution :THEFREE ENERGY`(Delta_ rG ^(@) ) `ofthereaction=`Delta G ^(@) ` ( products )-`Delta G^(@) ` (reactants)
` ""=Delta G ^(@) ( Zn O )+[ DeltaG^(@) (SO_2 ) ] -Delta G^(@)(ZNS) `
`""=(-480)+(-544) - (-293) KJ`
`""=-1024 +293 k J=-731 k J`
Since` Delta _ rG^(@) `ofthereaction- ve,therefore, thisreactionisfeasibleat1073 K.
