Question

Can you please show how you compare equation 1 and equation 2? How did the change in enthalpy became -73.1 J and change in entropy became -42.8 J/K.

The Gibbs free eneigy change is :
AG = AH- TAS
%3D
Given equation is'.
AG
ー 731 +42.8 T
AG - -73.1 J + 42.8 TJ
ド
Compare equa h'ons O and 2 . Then
AH =-73-I I
As = - 42. 8J
%3D
AH value is negative · Tuis
means thet beat eneigy rel eased
in the Techon. 30 the product has lowet entralpy value than
the reactaut.
