Graphite is more stable than diamond due to its lower energy state and stronger thermodynamic stability under standard conditions. In graphite, carbon atoms are arranged in a planar structure with layers that can slide over each other, allowing for greater stability. In contrast, diamond's three-dimensional lattice structure creates more strain and higher energy, making it less stable. Additionally, the enthalpy of formation for graphite is lower than that of diamond, reinforcing graphite's stability at room temperature and pressure.
What else can I help you with?
Is graphite more stable thermodynamically than diamond?
It is, so diamond will become graphite over time. The structure of diamond hinders the necessary kinetics, so the process is very slow, unnoticeable most of the time. It's because the standard enthalpy of formation of graphite is 0; but diamonds is not equal to 0.
What is the most inert form of carbon?
Graphite is the most thermodynamically stable (more than diamond).
Who is better thermal conductor diamond or graphite?
Diamond is a better thermal conductor than graphite. This is because diamond has a more orderly structure with tightly packed atoms, allowing heat to flow easily through the material. Graphite, on the other hand, has a layered structure with weak interlayer forces that hinder the flow of heat.
What can graphite be scratched by?
Graphite can be scratched by materials that are harder than it, such as diamond and tungsten.
What makes diamonds and graphite two forms of the element carbon so different?
Well to be very upfront diamond is very heated and compressed carbon (coal graphite) while graphite is more "pure" carbon than diamonds

Graphite is more common than diamond?
Yes, graphite is more common than diamond.
What is the most inert form of carbon?
Graphite is the most thermodynamically stable (more than diamond).
Why diamond and graphite forms of carbon evolve of different amounts of heat on combustion?
Diamond is more stable than graphite due to its strong covalent bonds, requiring more energy to break these bonds during combustion, resulting in less heat evolution. Graphite has weaker van der Waals forces between its layers, making it easier to break apart and leading to more heat evolution during combustion.

Which has the less density graphite or diamond?
Graphite is less dense than diamond, due to the differences in crystal structure.
Why does diamond have a greater density than graphite?
Diamond has a greater density than graphite because it has a crystal structure where each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement, making it tightly packed and more dense. In contrast, graphite has a layered structure with weak forces between the layers, resulting in a lower density.
What can exist in more than one form in the same state iron neon iodine or carbon?
Carbon: diamond, graphite, glassy graphite, graphene, fullerene etc.
What elements have more than one form?
Carbon, sulfur, and phosphorus are examples of elements that exist in more than one form. For example, carbon can be found as diamond or graphite, sulfur can be found as rhombic or monoclinic, and phosphorus can be found as white or red.
