Question

A chemist designs a galvanic cell that uses these two half-reactions:

half-reaction	standard reduction potential
CrO2−4 (aq)+4H2O(l)+3e−→ CrOH3(s)+5OH−(aq)	=E0red−0.13V
Cl2(g)+2e−→ 2Cl−(aq)	=E0red+1.359V

Answer the following questions about this cell.

Write a balanced equation for the half-reaction that happens at the cathode.

Write a balanced equation for the half-reaction that happens at the anode.

Write a balanced equation for the overall reaction that powers the cell. Be sure the reaction is spontaneous as written.

Do you have enough information to calculate the cell voltage under standard conditions?

If you said it was possible to calculate the cell voltage, do so and enter your answer here. Be sure your answer has the correct number of significant digits.
