Exactly 0K is an unattainable temperature. Temperatures can approach absolute zero but not be absolute zero. One of the ways to study very fast reactions is to cool them down to a few degrees above absolute zero where they occur at a rate where they can be studied.

Why all the comments about "no movement" at absolute zero? Absolute zero "USED" to be describe as the temperature where all molecular motion ceased, but that has long since been replaced by the statement that absolute zero is the temperature where kinetic energy (energy of motion) reaches its minimum, which need not be zero (the zero-point energy).

Also,
zero kelvin is absolute zero, complete cessation of all movement (including sub-atomic particles) No electron movement = no chemical reaction. at all.
