The direction of physical time is determined by expansion of the universe (which allows entropy to increase) - which in a sense is a gravitational effect.

What would be observationally different in a contracting or steady state universe?
Depends. If it contracted enough it would reach the maximum possible entropy density and everything would be in thermal equilibrium (and very hot). We're possible because the rapid expansion of the universe provides an entropy sink, so we can live off the far-from-equilibrium radiation from the Sun.
Can the Hubble constant or the cosmological constant be deduced from a thermodynamic measurement, perhaps some chemistry experiment?
No by any theory I know of.

Suppose the universe were contracting at the same rate it is expanding. What would be observationally different concerning the increase of entropy in ordinary laboratory measurements. If nothing different, then in what sense is the statement "The direction of physical time is determined by expansion of the universe (which allows entropy to increase)" anything other than a collection words strung together into a grammaticaly correct English sentence?
