Chemical Thermodynamics Question 222
Question: Which of the following equations correctly represents the standard heat of formation $ (\Delta H_{f}^{o}) $ of methane [IIT JEE (Screening) 1992]
Options:
A) $ C(diamond),+2H_2(g)=CH_4(g) $
B) $ C(graphite)+2H_2(g)=CH_4(l) $
C) $ C(graphite)+2H_2(g)=CH_4(g) $
D) $ C(graphite)+4H=CH_4(g) $
Show Answer
Answer:
Correct Answer: C
Solution:
$ {C_{(graphite)}}+2{H_{2(g)}}=C{H_{4(g)}} $ .
