(a) 
(b) 
Explanation:
Hello,
(a) In this case, for the given chemical reaction, the law of mass action becomes:
![Kc=\frac{[C6H5CHO][H2]}{[C6H5CH2OH]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BC6H5CHO%5D%5BH2%5D%7D%7B%5BC6H5CH2OH%5D%7D)
In such a way, as 1.20 g of benzyl alcohol are placed into a 2.00-L vessel, the initial concentration is:
![[C6H5CH2OH]_0=\frac{1.20g*\frac{1mol}{108.14g} }{2.00L} =5.55x10^{-3}M](https://tex.z-dn.net/?f=%5BC6H5CH2OH%5D_0%3D%5Cfrac%7B1.20g%2A%5Cfrac%7B1mol%7D%7B108.14g%7D%20%7D%7B2.00L%7D%20%3D5.55x10%5E%7B-3%7DM)
Hence, by writing the law of mass action in terms of the change 
due to equilibrium:
Solving for by using a quadratic equation one obtains:
Thus, the equilibrium concentration of benzyl alcohol is computed:
![[C6H5CH2OH]_{eq}=5.55x10^{-3}M-5.50x10^{-3}M=5x10^{-5}M](https://tex.z-dn.net/?f=%5BC6H5CH2OH%5D_%7Beq%7D%3D5.55x10%5E%7B-3%7DM-5.50x10%5E%7B-3%7DM%3D5x10%5E%7B-5%7DM)
With that concentration the partial pressure results:
![p_{C6H5CH2OH}=[C6H5CH2OH]_{eq}RT =5x10^{-5}\frac{mol}{L} *0.082\frac{atm*L}{mol*K}*523K \\p_{C6H5CH2OH}=2.14x10^{-3}atm](https://tex.z-dn.net/?f=p_%7BC6H5CH2OH%7D%3D%5BC6H5CH2OH%5D_%7Beq%7DRT%20%3D5x10%5E%7B-5%7D%5Cfrac%7Bmol%7D%7BL%7D%20%2A0.082%5Cfrac%7Batm%2AL%7D%7Bmol%2AK%7D%2A523K%20%5C%5Cp_%7BC6H5CH2OH%7D%3D2.14x10%5E%7B-3%7Datm)
(b) Now, the fraction of benzyl alcohol that is dissociated relates its equilibrium concentration with its initial concentration:
Best regards.
The first bond between two atoms is always a sigma bond and the other bonds are always pi bonds and a hybridized orbital cannot be involved in a pi bond. Thus we need to leave one electron (in case of Carbon double bond) to let the Carbon have the second bond as a pi bond.
<span>Ionic compounds are chemical compounds in which ions are held together in a lattice structure by ionic bonds. They have a high melting and boiling point, and they have a high hardness and are very brittle. The cations and anions are stuck together in a sense. So in this case, sodium (Na) is attracted to Chlorine (Cl).</span>
<span>A. It increases the number of collisions between molecules.
I hope this helps :)</span>
Answer:
Kf = 1.11x10¹³
Explanation:
The value of Kf for a multistep process that involves an equilibrium at each step, is the multiplication of the constant of the equilibrium of each step.
Kf = K1xK2xK3xK4
Kf = 1.90x10⁴ x 3.90x10³ x 1.00x10³ x 1.50x10²
Kf = 1.11x10¹³
