3) Predict whether the change in entropy is positive, negative, or zero for each of the following reactions at 298 K, and explain your reasoning (2 pts each. 8 pts total): 1.4 Fe(s) + 3 O2(g) → 2 Fe:O:(s) b. O(g) + ( ) → O.(g) NH,Cl(s) » NH(g) + HCl(g) d. Hz(g) + Cl:(g) → 2 HCI c.
Short Answer: (4 points each) 1.) Predict whether the entropy change is positive or negative for each of the following reactions. GIVE YOUR REASON FOR YOUR PREDICTIONS a) 2KC1O4(s) → 2KCIO3() + O2(8) b) H2O → H2O) c) 2Na(3) + H2O → 2NaOH(aq) + H2() d) N2(g) → 2N) 2.) State whether the sign of the entropy change expected for each of the following processes will be positive or negative, and EXPLAIN YOUR PREDICTIONS. a) PC130) + Cl2(e) → PCls(s)...
