An electrochemical cell is made from two half cells. The first contains 1M hydrochloric acid above 1 atm Cl2gas (w/ a platinum electrode). The other half cell contains a solution of H2O2 above 1 atm of O2 (also with a platinum electrode). A spontaneous reaction occurs.

a. Write the balanced redox reaction

(having trouble figuring this out)

What about
Cl2 + H2O2 ==> 2Cl^- + O2 + 2H^+
I don't know if this is the spontaneous direction or the reverse but you can look up the Eo potentials and decide which direction to write it.
