hi there
i was wondering could someone please get an answer to the following questions and compare them with mine its just revision for a test but i need to make sure i am on the riht track i got a,c repsectivily cheers
Consider an electrochemical cell where the following reaction takes place:
2Al(s) + 3Fe2+(aq) 2Al3+(aq)+ 3Fe(s)
Which of the following is the correct cell notation for this cell?
a. Al | Fe2+ || Al3+ | Fe
b. Al | Al3+ || Fe2+ | Fe
c. Fe | Fe2+ || Al3+ | Al
d. Al3+ | Al|| Fe | Fe2+
By consulting Eo tables determine the cell potential at 25oC for a cell having the following reaction:
Zn(s) + Cu2+(aq)Zn2+(aq)+ Cu(s)
when [Cu2+] = 0.100 M and [Zn2+] = 1.00 M. Use R = 8.3145 kPa.L/mol.K and F = 96500C/mol
a. -1.14 V
b. -0.42 V
c. +1.07 V
d. +1.10 V
