Question
What is the sign of the entropy change in eaech chemical reaction?
a) N2O4(g)--> 2NO2(g)
b) PCl3(g) + Cl2(g) --> PCl5(g)
c) 2 Al(s) + 3/2 O2(g) --> Al2O3(s)
d)N2(g) + 3H2(g) --> 2 NH3(g)
e) S(s) + O2(g) --> SO2(g)
a) N2O4(g)--> 2NO2(g)
b) PCl3(g) + Cl2(g) --> PCl5(g)
c) 2 Al(s) + 3/2 O2(g) --> Al2O3(s)
d)N2(g) + 3H2(g) --> 2 NH3(g)
e) S(s) + O2(g) --> SO2(g)

a) N2O4 = 304.2 J/mol*K
NO2 = 240.0
(2*240.0) - 304.2 = +
Check my numbers. I have trouble reading them from my table.
The others are done the same way.
