To determine the temperature above which the reduction of lead oxide (PbO) to lead (Pb) becomes spontaneous, we can use the Gibbs free energy equation: \[ \Delta G = \Delta H - T \Delta S \] ### Step 1: Understand the conditions for spontaneity For a reaction to be spontaneous, \(\Delta G\) must be less than 0. At the temperature where the reaction becomes spontaneous, \(\Delta G\) will equal 0. Therefore, we can set up the equation: ...
