Find out the change in the moles of gas for each of the following reactions and decide if the entropy increases, decreases, or has little or no change.
a) K(s) + O2(g) yields KO2(s)
Delta n gas = ?mol delta S rxn? Increases, decreases, has little or no change
b) CO (g) + 3H2(g) yields CH4(g) + H2(g)
Delta n gas=? mol delta S rxn? Increases, decreases, has little or no change
c) C2H2(g)+3O2(g) yields 2CO2(g)+2H2O(l)
Delta n gas=? mol delta S rxn? Increases, decreases, has little or no change
d) N2O2 (g) yields 2NO(g) + O2(g)
Delta n gas= ?mol Delta S rxn? Increases, decreases, has little or no change
