At a certain temperature, the equilibrium constant, Kc, for this
reaction is 53.3. At this temperature, 0.500 mol of H2 and 0.500
mol of I2 were placed in a 1.00-L container to react. What
concentration of HI is present at equilibrium?
The equilibrium constant, K , of a reaction at a
particular temperature is determined by the concentrations or
pressures of the reactants and products at equilibrium.
For a gaseous reaction with the general form
aA+bB⇌cC+dD
the Kc and Kp expressions are given by
Kc=[C]c[D]d[A]a[B]b
Kp=(PC)c(PD)d(PA)a(PB)b
The subscript c or p indicates whether K is expressed
in terms of concentrations or pressures. Equilibrium-constant
expressions do not include a term for any pure solids or liquids
that may be involved in the...
At a certain temperature, this reaction establishes an
equilibrium with the given equilibrium constant Kc.
