A chemical reaction is taking place between two reactants dissolved in a liter of water. If an additional liter of pure water is added to the reaction mixture, what will be the effect on the reaction rate?

We often want to decrease the rates of certain reactions rather than speeding them up. For example, to prolong the shelf lives of certain foods, the chemical reactions by which they spoil must be slowed down. How can this be accomplished by using the factors introduced in the video above?

Grain dust is highly explosive, as seen in the link above. Before they are ground up into flour, whole grains like wheat are flammable, but not explosive. What is causing the grain to react so much faster after it has been milled?

An aqueous reaction is taking place in a liter of water that is being stirred in a 5-liter flask. If the entire reaction was transferred to a 2-liter flask, what would be the effect on the overall reaction rate?
