At what minimal temperature is the following reaction, the reduction of magnetite by graphite to elemental iron, spontaneous?
Fe3O4(s)+2C(s,graphite)→2CO2(g)+3Fe(s)

Respuesta :

The values of  enthalpy change, entropy change and  temperature all determine the spontenity of a reaction.

What is a sponteanous reaction?

A sponteanous reaction is one which has the change in free energy as negative. We know that ΔG = ΔH - TΔS. The spontenity of a reaction depends on;

i. enthalpy change

ii. entropy change

iii. temperature

Since the values in the qestion are not given, the question is incomplete and we can not obtain a numerical value in order to decide the sponteanity of the reaction.
