I am currently reading cosmology and I read the statement "... chemical
potential which is nearly always negligible when processes are in equilibrium."
So the current understanding I got of chemical potential is through the law:
$$dE = - pdV + TdS + \mu dN.$$
Hence for processes which occur at constant volume and without heat transfer
$$\frac{\partial E}{\partial N} = \mu$$
indicating that $$\mu$$ is the work done on the system in transferring one particle to it.
Now, why is this energy negligible at equilibrium?
