Chemical Thermodynamics Question 175
Question: The heat of transition $ (\Delta H_{t}) $ of graphite into diamond would be, where $ C(graphite)+O_2(g)\to CO_2(g);\Delta H=x,kJ $
$ C(diamond),+C_2(g)\to CO_2(g);\Delta H=y,kJ $ [Pb. PET 1985]
Options:
A) $ (x+y),kJ,mo{{l}^{-1}} $
B) $ (x-y),kJ,mo{{l}^{-1}} $
C) $ (y-x),kJ,mo{{l}^{-1}} $
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
Graphite $ \xrightarrow{{}} $ diamond $ \Delta H_{t}=(x-y),kJ,mo{{l}^{-1}} $ .
