Answer :
The equilibrium concentration of CO is, 0.016 M
The equilibrium concentration of Cl₂ is, 0.034 M
The equilibrium concentration of COCl₂ is, 0.139 M
Explanation :
The given chemical reaction is:

Initial conc. 0.1550 0.173 0
At eqm. (0.1550-x) (0.173-x) x
As we are given:

The expression for equilibrium constant is:
![K_c=\frac{[COCl_2]}{[CO][Cl_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCOCl_2%5D%7D%7B%5BCO%5D%5BCl_2%5D%7D)
Now put all the given values in this expression, we get:

x = 0.139 and x = 0.193
We are neglecting value of x = 0.193 because equilibrium concentration can not be more than initial concentration.
Thus, we are taking value of x = 0.139
The equilibrium concentration of CO = (0.1550-x) = (0.1550-0.139) = 0.016 M
The equilibrium concentration of Cl₂ = (0.173-x) = (0.173-0.139) = 0.034 M
The equilibrium concentration of COCl₂ = x = 0.139 M

write the overall rate law for the initial rate of the reaction as a fraction.
Rate=k(________/_________)
Answer:
The overall rate law for the initial reaction is = ![k_{overall} [H_{2}SO_{4}]^{2} [C_{6}H_{6}]](https://tex.z-dn.net/?f=k_%7Boverall%7D%20%5BH_%7B2%7DSO_%7B4%7D%5D%5E%7B2%7D%20%5BC_%7B6%7DH_%7B6%7D%5D)
Explanation :
Frist of all, all the common terms are cancelled out and written the overall reaction.
As we know that the rate depednant step is the slowest step of the reaction, rate law is :
rate = ![k_{2} [SO_{3}][C_{6}H_{6}]](https://tex.z-dn.net/?f=k_%7B2%7D%20%5BSO_%7B3%7D%5D%5BC_%7B6%7DH_%7B6%7D%5D)
But the problem is that SO3 cannot be written in the overall rate law because it is an intermediate.
Rate law for synthesis of S03 is as follows :
rate = ![k_{1}[H_{2}SO_{4}]^{2}](https://tex.z-dn.net/?f=k_%7B1%7D%5BH_%7B2%7DSO_%7B4%7D%5D%5E%7B2%7D)
Hence when we substitute equation 2 in equation one,
Rate comes out to be = ![k_{overall} [H_{2}SO_{4}]^{2} [C_{6}H_{6}]](https://tex.z-dn.net/?f=k_%7Boverall%7D%20%5BH_%7B2%7DSO_%7B4%7D%5D%5E%7B2%7D%20%5BC_%7B6%7DH_%7B6%7D%5D)

Electron - In an atom, the central part which is composed of neutrons and protons including quarks is called the nucleus. Whereas the electron is the particle with negative elementary electric charge can be found inside the atom surrounding the nucleus.
