Q: Addition of an inert substance (one that does not participate in

Addition of an inert substance (one that does not participate in the reaction) does not change the of an equilibrium.

Q: When the volume of a vessel containing a gaseous equilibrium system is

When the volume of a vessel containing a gaseous equilibrium system is decreased, the of the gaseous substances present is initially increased.

Q: What is meant by the solubility product for a sparingly soluble salt

What is meant by the solubility product for a sparingly soluble salt? Choose a sparingly soluble salt and show how the salt ionizes when dissolved in water, and write the expression for its solubility...

Q: Many sugars undergo a process called mutarotation, in which the sugar

Many sugars undergo a process called mutarotation, in which the sugar molecules interconvert between two isomeric forms, finally reaching an equilibrium between them. This is true for the simple sugar...

Q: For the reaction CaCO3(s) ⇌ CaO(s

For the reaction CaCO3(s) ⇌ CaO(s) + CO2(g) the equilibrium constant K has the form K = [CO2]. Using a handbook to find density information about CaCO3(s) and CaO(s), show that the concentrations of...

Q: When writing a chemical equation for a reaction that comes to equilibrium

When writing a chemical equation for a reaction that comes to equilibrium, how do we indicate symbolically that the reaction is reversible?

Q: How does the collision model account for the fact that a reaction

How does the collision model account for the fact that a reaction proceeds faster when the concentrations of the reactants are increased?

Q: How does an increase in temperature result in an increase in the

How does an increase in temperature result in an increase in the number of successful collisions between reactant molecules? What does an increase in temperature mean on a molecular basis?
