Consider the reaction.
A(aq)↽−−⇀3B(aq)Kc=4.30×10−6at 500 K
If a 4.90 M sample of A is heated to 500 K, what is the concentration of B at equilibrium?
[B]= ? M
--- At a certain temperature, the equilibrium constant for the chemical reaction shown is 6.13×10−3. At equilibrium, the concentration of AB is 2.125 M, the concentration of BC is 2.925 M, and the concentration of AC is 0.250 M. Calculate the concentration of B at equilibrium.
AB(aq)+BC(aq)↽−−⇀AC(aq)+2B(aq)
[B] = ? M
