Calculate DeltaG_(r)^(@) of the following reaction Ag^(+)(aq)+cI^(-)(aq)rarrAgCI(s) Given DeltaG_(r)^(@)(AgCI)rarr109 kJ Mol^(-1) DeltaG_(r)^(@)(CI^(-))rarr-129 kJ Mol^(-1) DeltaG_(r)^(@)(ag^(-))rarr77 kJ Mol^(-1) (i)Represent the above reaction in form of a cel (ii) Calcualte E^(@) of the cel (iii) Find log_(10)K_(sp) of AgCI

Answer»

`68 kj mol^(-)`
(i) `AG(s)|Ag^(+)||AgCI||CI^(-)|CI_(2),pt`
(ii) `E_(cell)^(@)=0.89V`
(iii)`log_(10)K_(sp)=-10`
`82 kj mol^(-)`
(i) `Ag(s)|Ag^(+)||AgCI||CI^(-)|CI_(2),pt`
(ii) `E_(cell)^(@)=0.59V`
(iii)`log_(10)K_(sp)=-8`
`57 kj mol^(-)`
(i) `Ag(s)|Ag^(+)||AgCI||CI^(-)|CI_(2),pt`
(ii) `E_(cell)^(@)=0.59V`
(iii)`log_(10)K_(sp)=-10`
`69 kj mol^(-)`
(i) `Ag(s)|Ag^(+)||AgCI||CI^(-)|CI_(2),pt`
(ii) `E_(cell)^(@)=0.52V`
(iii)`log_(10)K_(sp)=-4`

SOLUTION :`57 kj mol^(-)`
(i) `Ag(s)|Ag^(+)||AgCI||CI^(-)|CI_(2),pt`
(ii) `E_(cell)^(@)=0.59V`
(iii)`log_(10)K_(sp)=-10`
