A) \[x>y\]
B) \[x<y\]
C) \[x=y\]
D) \[xy\]
Correct Answer: A
Solution :
\[C{{H}_{4}}(g)+\frac{1}{2}{{O}_{2}}(g)\xrightarrow{{}}C{{H}_{3}}OH(l)\] |
\[\therefore \]\[\Delta H=-\,\,[(\Delta H\,\text{of}\,\text{combustion}\,\text{of}\,C{{H}_{3}}OH)\] |
\[-\,(\Delta H\,\text{of combustion of }C{{H}_{3}})]\] |
\[=-[(-y)-(-x)]\] |
\[=-[-y+x]=y-x\] |
\[\therefore \] \[x>y\] |
