Question

The Gibbs free energy change of a reaction at 27°C is --26 kCal. and its entropy change is -60 Cals/K. AH for the reaction is :
0 -44 kcal
0-18 kcal
O 34 kcal
O - 24 kcal

Answer 1

Answer:

-44 Kcal

Explanation:

as we know

∆G=∆H-T∆S

on solving (temp is 300 K)

∆H=∆G+T∆S

= -26000+300 (-60)

= -26000-18000

= -44Kcal
