Question

2 HCl (9)

=H2(g) + Cl2 (9)
K = [H][CI]/[HCI)
UK = [H][CI]/2[HCI]
K = 2[HC]/[H]CI.)
K = [HCI)?/[H][1]

Answer 1

(K) = [H2] [Cl2] / [HCl]²

Step-by-step explanation:

The equation of the reaction is given as;

2 HCl (g) ⇔ H2 (g) + Cl2 (g)

The Equilibrium constant is the ratio of the concentration of the products and reactants raised to the power of their coefficients

Products = H2 and Cl2

Reactants = HCl

Equilibrium constant (K) = [H2] [Cl2] / [HCl]²
