Answer:
The value of the equilibrium constant = 5.213
Explanation:
Here 
(equilibrium constant) is referred to as the partial pressure of product divided by the partial pressure of reactant with each pressure term raised to power that is equal to its stoichiometric coefficient in balanced equation
.
As such only gas appear in expression as solids takes a value of 1;
SO ; in the given equation from the question:
2 A (g) + B (s) ----> 2 C(s) + D (g)
![K_p = \dfrac{[D]}{[A]^2}](https://tex.z-dn.net/?f=K_p%20%3D%20%5Cdfrac%7B%5BD%5D%7D%7B%5BA%5D%5E2%7D)
The value of the equilibrium constant = 5.213
<span>The correct answers are A, B, and D. The ΔHrxn is equal to the ΔHf when the ΔHf of the reactants is zero, and this can only occur when the reactants are pure elements (not compounds) in their natural phase at ambient temperature.
c) Chlorine's natural phase is gaseous, but since it is a liquid in this reaction, ΔHf ≠ 0.
e) CO is a compound, not a pure element.
f) BaCO3 is a compound, not a pure element.</span>
