Answer:
k = 8,83x10³⁹
Explanation:
For the reaction:
CO₂(g) + 2H₂(g) ⇌ CH₃OH(l)
ΔG° = ΔGproducts - ΔGreactants
ΔG° = ΔGCH₃OH(l) - (ΔGCO₂(g) + 2ΔGH₂(g)
As ΔGCH₃OH(l) = -166,4 kJ/mol; ΔGCO₂(g) = -394,4 kJ/mol; ΔGH₂(g) = 0 kJ/mol
ΔG° = -166,4 kJ/mol - (-394,4 kJ/mol + 2×0 kJ/mol)
ΔG° = 228,0 kJ/mol
The ΔG could be defined as:
ΔG = -RT lnK
Where R is gas constant (8,314472x10⁻³ kJ/molK); Temperature is 25°C, 298,15K.
Replacing:
228,0 kJ/mol = 8,314472x10⁻³ kJ/molK×298,15K ln K
91,97 = ln k
K = 8,79x10³⁹ ≈ 8,83x10³⁹

Answer: The equilibrium constant, 
, for the reaction is 0.061.
Explanation:
Initial concentration of 
= 
Equilibrium concentration of = 
The given balanced equilibrium reaction is,
Initial conc. 0.039 M 0 M 0 M
At eqm. conc. (0.039-x) M (x) M (x) M
Given : (0.039-x) = 0.012
x = 0.027
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[Cl_2]\times [PCl_3]}{[PCl_5]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCl_2%5D%5Ctimes%20%5BPCl_3%5D%7D%7B%5BPCl_5%5D%7D)
Now put all the given values in this expression, we get :
The equilibrium constant, , for the reaction is 0.061.

not 100% but hope it helped kinda
Answer:
According to Thompson's model, Every atom consists of a positively charged sphere of radius 10-- 10m in which entire mass and positive charge of the atom are uniformly distributed inside the sphere electrons are embedded like seeds in watermelon. According Rutherford entire poistive charge and mass of the atom are concentrated in a tiny central core of the atom which is called atomic nucleus contains. Size of nucleus = 10-- 15m. The nucleus contains protons and neutrons. Negatively charged electrons revolve around the nucleus in circular orbits.
