Use the tabulated half-cell potentials below to calculate the
equilibrium constant (K) for the following balanced redox reaction
at 25°C. Pb2+(aq) + Cu(s) → Pb(s) + Cu2+(aq)
Combining Equilibrium Constants.
It is possible to predict the equilibrium constant of a reaction
by combining two or more reactions for which the value of
K is known. When combining equilibrium constants, it is
important to note the following:
When a reaction is reversed, its Kvalue is inverted;
that is, Kreverse=1/Kforward.
When the coefficients of a reaction are multiplied by a factor,
the Kvalue is raised to the power of that factor.
When reactions are added, their Kvalues are
multiplied....
