Answer must be explained

3. Which reaction would have the most positive AS°?
(A) CO(g) + 2H2(g) → CH;OH(1)
(B) 2CH;OH(g) + 302(g) → 20CO2(g) + 4H,0(g)
(C) HC1(g) + NH3(g) → NH,Cl(s)
(D) Ba(OH)2 · 8H;O(s) + 2NH,NO3(s) →
Ba(NO3)2(s) + 2NH3(g) + 10H,0(1)

Expert Solution

Step 1

Interpretation: Which reaction would have the most positive $∆ S °$ , is to be determined.

Given reactions:

$(A) CO (g) + 2 H_{2} (g) \to {CH}_{3} OH (l) (B) 2 {CH}_{3} OH (g) + 3 O_{2} (g) \to 2 {CO}_{2} (g) + 4 H_{2} O (g) (C) HCl (g) + {NH}_{3} (g) \to {NH}_{4} Cl (s) (D) Ba {(OH)}_{2} \cdot 8 H_{2} O (s) + 2 {NH}_{4} {NO}_{3} (s) \to Ba {({NO}_{3})}_{2} (s) + 2 {NH}_{3} (g) + 10 H_{2} O (l)$
