How to use Le Chatelier's principle to predict the effect of a change in concentration on the equilibrium position and on K?
Solutions
Expert Solution
Le Chatelier's Principle: The dynamic equilibrium is disturbed by changing the conditions like concentration, pressure, temperature etc., the position of equilibrium moves to counteract the change.
Consider an equilibium reaction A+2B <===> C+D
the equilibrium constant K=[C][D]/[A][B]2
=> If you increase the concentration of A, the position of equilinrium will move to counteract means it will move so the concentration of A decreases again by reacting with B and forming C and D. The position of equilibrium moves to the right.
=> The value of K is increases as the [A] decreses because K is inversely proportional to [A].
=> If you decrease the concentration of A, the position of equilinrium will move to counteract means it will move so the concentration of A increases again. That means that more C and D will react to replace the A that has been removed.
=> The position of equilibrium moves to the left.
=> The value of K is decreases as the [A] decreses because K is inversely proportional to [A].

1.) Explain the following observations in terms of shifting
equilibria by Le Chatelier's Principle. Write the equation for the
equilibrium involved in each case.
a.) barium chromate, BaCrO4, is insoluble in basic solution but
dissolves readily in acidic solution.
b.) The addition of NaOH to the iron (III)- thiocyanate
equilibrium causes the red color to disappear and a rust colored
precipitate to form.

An experiment with Le Chatelier's Principle resulted in this
equation: Fe3+ + SCN- <=> Fe(SCN)2+
First off, should the first reactant be Fe2+ or Fe3+? Our TA
said Fe2+, but I'm not sure why it's not Fe3+ since we were adding
Fe3+ to observe changes in equilibrium. (The lab manual specifies
that Fe(SCN)2+ in a product.)
Second, it was obvious that adding Fe3+ and SCN- shifted the
equilibrium to the right toward products. However, addition of
NaH2PO4 shifted the equilibrium...
