Hi,
Please help.

1) Equilibrium constant question:

Equilibrium constant.PNG

I am getting 0.294. What I did was i found the concentration of The solutions at the start. Then I calculated the change in concentration of h2. Then I subtracted the change in concentration of h2 from bromine gas original concentration. I doubled the value of change in concentration of h2 and used that for HBr and then found K.

Please tell me where I am going wrong and your solutions.

2) Also are the products of electrolysis of dilute NaCl, O^2 or Cl^2?

Why are you using concentration? Its asking for mol of bromine not concentration... I got 0.232

Products of electrolysis of dilute NaCl are hydrogen ions and oxygen at the anode. Cathode = Hydrogen gas and hydroxide ions.
