JEE Main 2022 · 26 June · Morning Shift · Chemistry · Electrochemistry
The ((∂ E)/(∂ T)) _ P of different types of half cells are as...
The _{P}\begin{cases}A & B & C & D \\ 1 \times {10}^{- 4} & 2 \times {10}^{- 4} & 0 . 1 \times {10}^{- 4} & 0 . 2 \times {10}^{- 4}\end{cases}E is the electromotive force). Which of the above half cells would be preferred to be used as reference electrode
Options
- A
- B
- C
- D
Correct answer
C.
Step-by-step solution
Metal Which have lower value of {\left(\dfrac{dE}{dT}\right)}_{p} is best used for standard or reference half Electrode because if can be used for wider range of temperature Without much derivation from standard Value.
