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 Absolute zero "USED" to be describe as the temperature where all molecular motion ceased, but that has long since been replaced by the statement that absolute zero is the temperature where kinetic energy (energy of motion) reaches its minimum, which need not be zero (the zero-point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.
