Redox reactions play a pivotal role in chemistry and biology. The values of standard redox potential `(E^(@))` of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited.
For the cell: Pt `|H_(2)(0.4"atm")H^(+)(pH=1)||H^(+)(pH=2)|H_(2)(0.1"atm")|` Pt, the measured potential at `25^(@)C` is:
[Given: 2.303RT/F=0.06V, log 2=0.3]

A

B

`-0.5V`

C

Redox reactions play a pivotal role in chemistry and biology. The values of standard redox potential (E^(@)) of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited. E^(@)(SRP) of different half cells are given below: E_(Cu^(2+)|Cu)^(@)=0.34V, E_(Zn^(2+)|Zn)^(@)=-0.76V E_(Ag^(+)|Ag=0.8V, E_(Mg^(2+)|Mg))=-2.37V In which cell, DeltaG^(@) per "mole" of electron is most negative?

Redox reactions play a vital role in chemistry and biology. The values of standard redox potential (E^(@)) of two half-cells reactions decide which way the reaction is expected to proceed. A simple example is a Daniell cell in which zince goes into solution and copper gets deposited.
