Calculate emf of the following cell at 25^ C if value of E_ cell ^ is 4 ~V (Given R T / F 10=0.06 ) : M |M_ (0.01 M ) ²⁺ | |M_ (0.0001 M ) ²⁺ | M
Options
- A3.94 ~V
- B4.06 ~V
- C2.03 ~V
- D8.18 ~V
Correct answer
A. 3.94 ~V
Step-by-step solution
aligned & E_ cell =E_ cell ^ - R T 2 F 0.01 0.0001 & =4- R T 2 F 10⁻² 10⁻⁴ =4- R T 2 F 10^2 & =4- R T F 10=4-0.06=3.94 ~V aligned
