Yes it may - at higher pressures.

The significance usually can be found in the necessity that often exists
to cross certain barriers (in free energy) that may be difficult to do
at room temperature. In a test-tube (i.e. experimental) setting, one may
be willing to wait seconds, minutes or hours but that is a luxury unavailable
to those who simulte... ;-)
