1 is an equation representing a solid reactant becoming a gaseous product, in other words resulting in more movement and therefore an increase in disorder. 1 is the best choice here.

Which equation represents a change that results in an increase in disorder? (1) I2 (s) = >I2 (g)

(2) CO2 (g) = >CO2 (s) (3) 2Na (s) + Cl2 (g) = >2NaCl (s)

(4) 2H2 (g) + O2 (g) = > 2H2O (l)
