WebFirst-order phase transitions such as graphite to diamond typically have a high activation barrier, and can only be seen by MD at pressures or temperatures exceeding those of equilibrium phase transition. Therefore, we used the excessive pressure to accelerate the phase transition in our MD simulation. WebQuestion: QUESTION 4 The enthalpy of the graphite + diamond phase transition, …
