say that I measured the voltage of electrochemical cells:

Zn/Cu: -0.961 V
Pb/Cu: -0.360 V
Ag/Cu: 0.425 V
Sn/Cu: -0.275 V
Fe/Cu:-0.516 V

Directions:
If you assign Cu an arbitrary electrode potential value of 0.00 V, the numbers above are the reduction potentials for the other metals. Then, rank each of the metals from highest to lowest tendency to be the anode. Include Cu as well.

Basically, the metals are Cu, Fe, Ag, Sn, Pb, and Zn. I have to find the Electrochemical cell of all related to Cu.

i know there's equation i have to use:Ecell = Ecathode − Eanode

I was wondering if you can just do an example of Cu and Fe and find the Elecrochemical cell related to copper.

Then i will do the rest.
My other question was after i find the numbers, what does it mean high to lowest. Would the biggest value of a metal have a high tendency to be an anode or a smaller tendency?

To determine the electrochemical cell related to copper (Cu) and iron (Fe), you need to calculate the cell potential (Ecell) by subtracting the anode potential (Eanode) from the cathode potential (Ecathode). In this case, Cu is the cathode, so its potential is 0.00 V.

Let's consider Cu (cathode) and Fe (anode):

Ecell = Ecathode - Eanode
= 0.00 V - (-0.516 V)
= 0.516 V

The positive value for Ecell indicates a spontaneous reaction where Cu acts as the cathode and Fe as the anode.

Now, to rank the metals from highest to lowest tendency to be the anode, you need to compare their reduction potentials (measured in volts). A higher reduction potential means a metal is more likely to be reduced (act as a cathode) and a lower reduction potential means a metal is more likely to be oxidized (act as an anode).

In this case, the reduction potentials you provided are:
Zn/Cu: -0.961 V
Pb/Cu: -0.360 V
Ag/Cu: 0.425 V
Sn/Cu: -0.275 V
Fe/Cu: -0.516 V

Ranking them from highest to lowest reduction potential (and, therefore, from highest to lowest tendency to be the anode) would be:

1. Ag/Cu: 0.425 V
2. Sn/Cu: -0.275 V
3. Pb/Cu: -0.360 V
4. Fe/Cu: -0.516 V
5. Zn/Cu: -0.961 V

Therefore, based on the reduction potentials, the metals in order of highest to lowest tendency to be the anode with respect to Cu are Ag, Sn, Pb, Fe, and Zn.
