Calculate the potential of the following cell `:`
`Pt(s)|{:(Ce^(3+),(2M)) ,(Ce^(4+),(1M)):}||{:(Cr^(3+)(2M),) ,(Cr_(2)O_(7)^(2-)(1M),H^(o+)(1M)):}|Pt(s)`
Given `:E^(c-)._(Ce^(3+)|Ce^(4+))=-1.7,E^(c-)._(Cr_(2)O_(7)^(2-)|Cr^(3+))=1.3V`
`(`Take`0.059~~0.06)`

Explanation

To calculate the potential of the given electrochemical cell, we will follow these steps:

### Step 1: Identify the half-reactions and their standard potentials
The cell is represented as:
\[ \text{Pt(s)} | \{ \text{Ce}^{3+} (2M), \text{Ce}^{4+} (1M) \} || \{ \text{Cr}^{3+} (2M), \text{Cr}_2\text{O}_7^{2-} (1M), \text{H}^+ (1M) \} | \text{Pt(s)} \]

Given standard reduction potentials:
