WebIt's not really necessary to calculate anything to rationalize why diamond would be the favoured allotrope at high pressure—diamond has a much higher density than graphite. At high pressure, the side of the equation with less volume will be favoured by Le Chatelier's principle. Share Improve this answer Follow answered Nov 23, 2014 at 19:30
