For the gaseous reaction of carbon monoxide and chlorine to form phosgene (COCl₂):(a) Calculate ΔS° at 298 K (ΔH° = -220kJ/mol and ΔG° = -206kJ/mol ).

Respuesta :

The value of ΔS° is -0.0469kJ/mol.K for the gaseous reaction of carbon monoxide and chlorine to create phosgene (COCl2).

The expression for the standard change in free energy is:

ΔG°= ΔH°- TΔS°

Where,

ΔG is the change in the Gibbs free energy.

T is the absolute temperature. (T in kelvins)

ΔH is the enthalpy change of the reaction.

ΔG is the change in entropy.

Given :

ΔS° at 298 K (ΔH° = -220kJ/mol and ΔG° = -206kJ/mol )

T=298K

ΔG°= ΔH°- TΔS°

ΔS° = ΔH° - ΔG°/T

      = -220 -(-206)/ 298

ΔS° = -0.0469kJ/mol.K
