Calculate Delta(r)G^(o) of the reaction ...

Calculate `Delta_(r)G^(o)` of the reaction `:`
`Ag^(o+)(aq)+Cl^(c-)(aq) rarr AgCl(s)`
Given `:Delta_(f)G^(o)._(AgCl)=-109kJ mol ^(-1)`
`Delta_(f)G^(o)_((Cl^(c-)))=-129k J mol ^(-1)`
`Delta_(f)G^(o)._((Ag^(o+)))=-77 kJ mol ^(-1)`

A

`-97 kJ mol^(-1)`

B

`-57kJ mol^(-1)`

C

`57kJmol^(-1)`

D

`97kJ mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
b
`Ag^(o+)(aq)+Cl^(c-)(aq)rarr AgCl(s)`
`Delta_(r)G^(c-)=Delta_(f)G^(c-)._((AgCl))-Delta_(f)G^(c-)._((Ag^(o+)))-Delta_(v)G^(c-)._((Cl^(c-)))`
`=-109-77-(-129)=-57kJ mol^(-1)`
