Equilibrium, Kinetics, Acids/Bases?
« on: May 30, 2013, 05:23:05 PM »
1. "The value of the equilibrium constant is affected by temperature...because...an increase in temperature causes more effective collisions to occur between the particles reacting"

Both clauses are true but they don't cause each other? Why not?

2. Which of the following would give the higher pH when dissolved to form a .10 M solution?
The answer is "the sodium salt of a weak acid" Why? Why is it not "A strong acid"?

3. Ammonium nitrate product dissolves in water at room temperature and the process causes the solution to become cold. Would the solubility increase if it was dissolved in warmer water since heat would be a reactant and shift the reaction to the right?

You have to show your attempts at solving the question to receive help. This is a forum policy.

1. "The value of the equilibrium constant is affected by temperature...because...an increase in temperature causes more effective collisions to occur between the particles reacting"

There are two reactions - forward and backward. Both are affected.
