A) \[x-y\]
B) \[2x+y\]
C) \[x+y\]
D) \[2x-y\]
E) None of the Above
Correct Answer: E
Solution :
(None): \[S+\frac{3}{2}{{O}_{2}}\xrightarrow{{}}S{{O}_{3}}+2x\,kJ\]...(i) \[S{{O}_{2}}+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}S{{O}_{3}}+y\,\,kJ\] ...(ii) \[S+{{O}_{2}}\xrightarrow{{}}S{{O}_{2}}+q\,\,kJ\] ...(iii) Equation (iii) can be obtained by subtracting equation (ii) from (i) \[\Rightarrow \] \[q=2x-y\,kJ\] Enthalpy of formation \[(\Delta {{H}_{f}})=-q=-(2x-y)\] \[=y-2x\]You need to login to perform this action.
