Use the standard reduction potentials to find the equilibrium constant for each of the following reactions at 25°c.
(a) 5 fe2+(aq) + mno4? (aq) + 8 h+(aq) < > mn2+(aq) + 4 h2o(l) + 5 fe3+(aq)
(b) 2 ce4+(aq) + 2 cl ? (aq) < > cl2(g) + 2 ce3+(aq)
(c) br2(l) + 2 i ? (aq) < > 2 br? (aq) + i2(s)

58750.08068 is the answer i think

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
