Question
The reversible chemical reaction A+B<-->C+D has the following equilibrium constant: Kc=4.6What is the final concentration of D at equilibrium if the initial concentrations are [A]=1.00M and [B]=2.00M? The reversible chemical reaction A+B<-->C+D has the following equilibrium constant: Kc=4.6
What is the final concentration of D at equilibrium if the initial concentrations are [A]=1.00M and [B]=2.00M?
What is the final concentration of D at equilibrium if the initial concentrations are [A]=1.00M and [B]=2.00M?
Explanation / Answer
A+B<-->C+D
kc = [C][D]/[A][B]
at equilibrium,
[A] = 1-x
[B] = 2-x
[C] = x , [D] = x
4.6 = x^2/((1-x)(2-x))
x = 0.86 M
at equilibrium , [c] = [D] = 0.86 M
