In a flask, colourless (g) is in equilibrium with brown coloured (g). At equilibrium when the flask is heated to 100℃, the brown colour deepens and on cooling it becomes coloured. Which statement is incorrect about this observation?
View answer and explanation
Correct option: C
The ∆H-∆U at 100℃ is equal to 200 cal
Option D (The ∆H-∆U at 100℃ is equal to 200 cal) is incorrect because the calculated value of ∆H-∆U is 746 cal, not 200 cal.
