related to diamond and graphite
« on: March 03, 2010, 04:23:32 AM »
as i know, the enthalpy change of diamond to graphite is only about -1.9kJ mol-1
but the activation energy is high so that the reaction is very slow
i am interested how long will a diamond change to graphite?
Anybody can answer?@@
thanks
