  The evolution of the electro-weak phase transition, including reheating due
to the release of latent heat in shock waves, is calculated for various values
of as yet unknown parameters of electro-weak theory such as latent heat and
bubble wall surface tension. We show that baryon production, which occurs in
the vicinity of the bubble walls of the phase transition, can be a sensitive
function of bubble wall velocity, and this velocity dependence is important to
include in the calculation of the baryon density of the universe. There is a
sensitive velocity dependence for all mechanisms of baryon production,
depending on the magnitude of velocity of the bubble wall, and we examine in
particular an inverse velocity dependence on baryon production, which is
predicted by the charge transport mechanism of baryon production. For this
mechanism we find both an enhancement of baryon production and the generation
of inhomogeneities during the electro-weak phase transition. We calculate the
magnitude of the baryon enhancement, which can be as large as a few orders of
magnitude, depending on the parameters of the theory, and we calculate the size
and amplitude of the inhomogeneities generated. We determine that the
inhomogeneities generated in a thermally nucleated electro-weak phase
transition are to small to survive diffusive processes and effect the
nucleosynthesis epoch. We also examine the possibility that a phase transition
nucleated by other means, such as by the presence of cosmic strings, may
produce inhomogeneities that could effect
