Homework Answers
A)
There are gases only on reactant side.
So, there is more entropy on reactant side than on product side.
So, there is decrease in entropy
Delta S will be negative
Answer: option 2
B)
ΔGo = ΔHo - T*ΔSo
For reaction to be spontaneous, ΔGo should be negative
Here:
ΔHo is negative
ΔSo is negative
ΔGo will be negative at low temperature.
So, reaction is spontaneous only at low temperature.
Answer: option 3
