Of the following reactions, which involves the largest increase in entropy? A) CaCO (s) --> CaO(s) + CO (g)
B) 2 CO(g) + O (g) --> 2 CO (g)
C) Pb(NO ) (s) + 2 KI(s) --> PbI (s) + 2 KNO (s)
D) C H (g) + 4 O (g) --> 3 CO (g) + 2 H O(g)
E) 4 La(s) + 3 O (g) --> 2 La O (s)

it should be all of them because it asks if you included all of those in your answer

explanation:

answerspecific gravity;

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
