Question
S + O2 + x kcal .......(1)
SO2 +
O2 → SO2 + y kcal .......(2)
The heat of formation of SO3 in the above reactior :
SO2 +
O2 → SO2 + y kcal .......(2)The heat of formation of SO3 in the above reactior :
Options
A.(x + y)
B.(x - y)
C.(2x - y)
D.(2x + y)
Solution
S = O2 → SO2 = x ......(i)
SO2 +O2 → SO3 + y ......(ii)
Adding (i) and (ii) we have
S + O2 + SO2 O2 → S O2 + S O3 + y
s +O2 → SO3
So, heat of information of SO3 will be (x - y).
SO2 +
O2 → SO3 + y ......(ii)Adding (i) and (ii) we have
S + O2 + SO2
O2 → S O2 + S O3 + ys +
O2 → SO3So, heat of information of SO3 will be (x - y).
