Problem 13.2: Where on the parametrized surface ~r(u; v) = [1 +
u3,v2,uv]T is the temperature T(x, y, z) = 2 + x + 12y - 12z minimal?
To nd the minimum, look where the function f(u; v) = T(~r(u, v)) has an
extremum. Find all local maxima, local minima or saddle points of f.

7. Given the standard reduction potential for the following two half-cell reactions (in the presence of 1.00 M HCl):

Fe3+ + e <==> Fe2+, E0 = + 0.68 V

AsO4 - + 2H+ + 2e <==> AsO3 - + H2O, Eo = +0.559 V.

Please calculate the system potential at the equivalence point when Fe3+ was used to titrate AsO3 - in the presence of 1.00 M HCl.
