1.) A voltaic cell utilizes the following reaction and operates at 298 K:
3Ce4+(aq)+Cr(s)→3Ce3+(aq)+Cr3+(aq).

What is the emf of the cell when [Ce4+]= 1.3×10−2 M ,[Ce3+]= 2.6 M , and [Cr3+]= 1.7 M ?

2.)Calculate the equilibrium constant K at 298 K:

Aqueous iodide ion is oxidized to I2(s) by Hg22+(aq)

In acidic solution, copper (I) ion is oxidized to copper (II) ion by nitrate ion

In basic solution, Cr(OH)3(s) is oxidized to CrO2−4(aq) by ClO−(aq)
