 need to make two graphs E ( volt) vs Temperature in Kelvin . The data is from a lab .

One graph is this cell Fe (s) [ Fe +2 (aq 1M) // Cu 2+ ( aq , 1 M) / Cu (s).

you have to choose from this data.

At 5 C (278 K) E = 0.62 V or 0.52 V

At 50 C ( 323 K) E = 0.35 V or 0. 75 V or 0.88 V

At 75 C( 348 K) E = 0.84V or 0.80 V

The you have to deternimate Detal G delta S and delta H.

then another graph of this cell

Zn( s) / Zn 2+ ( aq 1 M) // Cu 2+ ( aq , 1 M) / Cu (s)

At 5 C (278 K) E = 0.82 V or 0.61V

At 50 C ( 323 K) E = 0.77 V or 0. 83 V or 0.90 V

At 75 C( 348 K) E = 0.83 V or 0.69 V

Determinate delta G delta H and delta S.

2 Calculate the theorical values for Delta G , delta H and delta S and compare the to your results.

  • Thank you but its not what I asked in my question. I need to make two graphs with the data that I posted.

  • I don't know what are the proposed options. I need to see full instructions for this lab. Can you upload them here?
