Question

In which of the following equilibrium K꜀ and Kₚ are not
equal?
(a) 2 NO(g) ⇋ N₂ (g) + O₂ (g)
(b) SO₂ (g)+NO₂ (g) ⇋ SO₃(g) + NO(g)
(c) H₂(g)+I₂(g) ⇋ 2 HI(g)
(d) 2C(s)+O₂(g) ⇋ 2 CO₂(g)

Answer 1

Explanation:

For which of the following changes, ∆H≠∆U

(a) N₂ (g) + O₂ (g) → 2NO(g)

(b) H₂(g)+ Cl₂(g) → 2HCl(g)

(c) C(s)+ O₂(g) → CO₂(g)

(d) CaCO₃(s) → CaO(s) + CO₂ (g)✔️✔️

Answer 2

$\huge\mathbb\orange{Hello!!}$

(d) 2C(s)+O₂(g) ⇋ 2 CO₂(g)
