Chemical Thermodynamics Question 196
Question: The heat of formation of $ H_2O(l) $ is - 68.0 kcal, the heat of formation of $ H_2O(g) $ is likely to be
Options:
A) - 68.0 kcal
B) - 67.4 kcal
C) 80.0 kcal
D) - 58.3 kcal
Show Answer
Answer:
Correct Answer: B
Solution:
When $ H_2{O_{(l)}} $ is convert to form $ H_2{O_{(g)}} $ , heat is absorbed hence $ \Delta H_1>\Delta H_2 $ .
