An electrochemical cell consists of a standard hydrogen electrode and a copper metal electrode.

What is the potential of the cell at 298K if the copper electrode is palced in a solution in which [Cu2+] = 2.5e-4 M

Is the equation
2Cu(2+) H2 --> 2H+ + 2Cu+
with E0 = .16
I'm not sure what Q would be.
Q = [Cu+]^2
      [Cu2+]^2
Q = [Cu+]^2
       2.5e-4
I'm not sure what the concentration of Cu+ would be. Oh when they say copper electrode, is it Cu+ or Cu? Cause then my E0 might be different.

Show me what you have done first... then we can work from there.

      START WITH....
Give me the def. of Oxidation and the def. of Reduction.
Which elm gets oxidised and which gets reduced?
What is the formula for E0sel

What the copperelectode(Cu)? Is it a (s)or(aq)or(l)or(g)...think man.
