For the process 2SO2(g) + O2(g) --> 2SO3(g),

CaHeK987 [17]

Answer:

–187.9 J/K

Explanation:

The equation that relates the three quantities is:

$\Delta G = \Delta H - T \Delta S$

where

$\Delta G$ is the Gibbs free energy

$\Delta H$ is the change in enthalpy of the reaction

T is the absolute temperature

$\Delta S$ is the change in entropy

In this reaction we have:

ΔS = –187.9 J/K

ΔH = –198.4 kJ = -198,400 J

T = 297.0 K

So the Gibbs free energy is

$\Delta G=-198,400-(297.0)(-187.9)=254.2 kJ$

However, here we are asked to say what is the entropy of the reaction, which is therefore

ΔS = –187.9 J/K
