Hydrogen and oxygen combine to form water in a combustion reaction. The Gibbs energy for this reaction is negative at 773K. Is this reaction spontaneous? Explain why or why not.

Respuesta :

The reaction is spontaneous because the Gibbs free energy for the reaction is negative at the given temperature

Gibbs free energy

ΔG = ΔH – TΔS

Where

  • ΔG is the Gibbs free energy
  • ΔH is the enthalpy change
  • T is the temperature
  • ΔS is the change in entropy

NOTE

  • ΔG = +ve (non spontaneous)
  • ΔG = 0 (equilibrium)
  • ΔG = –ve (spontaneous)

Considering the question given above, we were told that the Gibbs free energy for the reaction is negative at 773 K.

Thus, we can conclude that the reaction is spontaneous at the given temperature.
