Answer:
-36.67 KJ
Explanation:
Now, we ,must find the E°cell as follows;
E°cell= E°cathode - E°anode
E°cathode= -0.25 V
E°anode = - 0.44 V
E°cell= -0.25 -(- 0.44) = 0.19 V
Equation of the reaction; Ni2+ (aq) + Fe(s) → Ni(s) +Fe2+ (aq)
Hence, n=2, there were two electrons transferred.
ΔG=-nFE°cell
ΔG= -(2 * 96,500 * 0.19)
ΔG= -36670 J
ΔG= -36.67 KJ
In polymer chemistry, polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them.
Answer:
C. They are inert and require a host cell.
Explanation:
Answer is:<span>value of Keq for the reaction is </span>1,6·10⁻⁵.
Chemical reaction: 2NOCI(g) ⇄ 2NO(g) + CI₂<span>(g).
</span>[NOCl] = 1,4·10⁻²<span> M.
[NO] = 1,2</span>·10⁻³<span> M.
[Cl</span>₂] = 2,2·10⁻³<span> M.
</span>K = [NO]² · [Cl₂] ÷ [NOCl]².
K = (1,2·10⁻³ M)² · 2,2·10⁻³ M ÷ (1,4·10⁻² M)².
K = 1,6·10⁻⁵.
