2) Calculate the enthalpy change for the conversion of graphite into diamond
C(Graphite) ----> C(Diamond)
Given the following thermochemical equations:
C(Graphite) + 2g O ---> 2 CO(g), H = 1.394 KJmol
C(Diamond) + 2g O ---> 2 CO(g), H = 1.394 KJmol
Step 1: Write the energy cycle
Step ii: Write the equation
H + -882 ---> -394 + 2(-286)
H + _____ ---> -394 + 2(-286) + 882
H =
KJmol
