predict the sign of the entropy change for each of the following processes:
a) I2(s)---->2I(g)
cannot predict
negative
positive
b) 2Zn(s) + O2 (g) ---> 2ZnO(S)
cannot predict
positive
negative
c) N2 (g) + O2(g) ---> 2NO(g)
negative
postive
cannot predict
Homework Answers
(a) I2(s) => 2 I(g)
Increase in number of gas particles => entropy increases => DS positive
(b) 2 Zn(s) + O2 (g) => 2 ZnO(S)
Decrease in number of gas particles => entropy decreases => DS negative
c) N2(g) + O2(g) => 2 NO(g)
No change in number of gas particles => cannot predict
