Question

What happens to the standard cell potential of a battery when temperature increases?

Answer 1

The value of Standard cell potential doesnot change with the change in temperature and is a constant.

Step-by-step explanation:

According to Nernst's equation:

`E=E_0-(RT)/(nF)log([reducing.agent])/([oxidizing.agent])`

where ,

• 
  `E` is the cell potential
• 
  `E_0` is the standard cell potential
• 
  `R` is the universal gas constant =
  `8.314 Jmol^(-1)K^(-1)`
• 
  `n` is the number of moles
• 
  `F` is the value of 1 faraday

• 
  `T` is the temperature.

As we see here ,
`E_0` is the standard cell potential and is only calculated at a particular temperature which is
`273K` .

Thus the value of
`E_0` doesnot change with the change in temperature and is a constant.
