A) (x + y)
B) (x - y)
C) (2x + y)
D) (2x - y)
Correct Answer: D
Solution :
[d]:\[S+3/2{{O}_{2}}\to S{{O}_{3}}+2x\,kcal\] ?(i) \[S{{O}_{2}}+1/2{{O}_{2}}\to S{{O}_{3}}+y\,kcal\] ?(ii) Now, subtract eq. (ii) from (i), we get \[S+{{O}_{2}}\to S{{O}_{2}}+2x-y\,kcal\] \[\therefore \]Heat of formation of \[S{{O}_{2}}\]is equal to 2x - y kcal.You need to login to perform this action.
