Determine standard cell potential for the voltaic cell

Question

The galvanic cell (voltaic cell) that uses the reaction:
  Cr₂O₇^2- (aq) + 6Fe²⁺ (aq)   + 14H⁺(aq) → 2Cr³⁺ (aq) + 6 Fe³⁺ (aq) + 7H₂O(l)

1.Write down the standard shorthand cell notation for the voltaic cell.

2. Determine standard cell potential for the voltaic cell
