Question

standard enthalpy of combustion of graphite at 25 centigrade is - 393kj/mole and that of diamond is - 395 enthalpy of graphite is​

Answer 1

Answer:

Carbon occurs in two forms: graphite and diamond. The enthalpy of combustion of graphite is -393.5 kJ, and that of diamond is -395.4 kJ.

And enthalpy of formation of carbon dioxide at 298.15K is -393.5 kJ/mol
