Kc = [b]*[c]/([a]^2) = (0.2 M)^2/(0.2 M)^2 = 1.0
To achieve equilibrium, Kc must be equal to 0.2, therefore Kc must decrease, so the concentrations of b and c must decrease and the concentration of a must increase, meaning the reaction will proceed toward the formation of a.
The greatest visual evidence you can use when trying to determine if a solution is saturated is to look and see if everything in the test tube is a single color and a single consistency.
It is true
I’ve done this before
<span> this represents the relative overall energy of each orbital, and the energy of each orbital increases as the distance from the nucleus increases</span>
