Question

What is “entropy” ? Give a useful definition.

In each of the following balanced chemical reactions, deduce whether the entropy change, ∆S, is positive or negative. Recall, ∆ always means final minus initial; so products minus reactants.

CO2(s) → CO2(g)        ∆S > 0, ∆S < 0    circle one 
NH3(g) + HCl(g) → NH4Cl(s)        ∆S > 0, ∆S < 0 circle one 
C2H6O (g) + 3 O2(g) → 2 CO2(g) + 3 H2O(l) ∆S>0, ∆S<0 circle one
