(1 pt) Predict whether the entropy change of the system in each of the following reactions is greater or less than zero for each of the following processes. Circle ∆ S>0 if the process increases entropy and circle ∆ S<0 if the process decreases entropy. (a) 2H 2 (g) + O 2 (g) . 2H 2 O( l ) ∆ S>0 or ∆ S<0 (b) NH 4 Cl(s) .
