Consider the equilibrium system
described by the chemical reaction
below. For this reaction, Kc = 2.1 x 10³
at a certain temperature. If the
equilibrium concentrations of H₂ and F₂
are both 0.0021 M, determine the
concentration of HF at equilibrium.
H₂(g) + F₂(g) 2 HF(g)
Kc =
[0.0021] 2[0.0021]
2[0.0011] [0.0011]³
Question 17 of 19
If [x] represents the equilibrium concentration
of HF, set up the equilibrium expression for Kc
to solve for the concentration. Each reaction
participant must be represented by one tile.
