WebFeb 18, 2024 · In the diamond oxidation reaction, two moles of water give three moles of gaseous reaction products. In this case, an increase in pressure in the reaction system will shift the equilibrium to the right side of the equation, and then the reaction rate should decrease. ... The equilibrium line graphite-diamond is presented according to Kennedy ... 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
