1- What are the factors that can influence the rate of a chemical reaction?

2- Why do the rates of most chemical reactions slow down over time?

3- What is the rule of thumb that relates a temperature change to the kinetics of a reaction? How does that rule relate to preventing food from spoiling by placing it in a refrigerator?

4- Sketch the activation energy diagram for a reaction with and without a catalyst present

5- Carbon monoxide is the flammable gas that is partially responsible for the muzzle flash seen from a firearm. It is also one of the gases that can cause a backdraft to happen when firefighters open up poorly ventilated rooms. Automobiles produce carbon monoxide as a result of the negative oxygen balance of the fuel-air explosion that powers the engines. Why does the carbon monoxide generated in a gun barrel or in a backdraft ignite, whereas there is no such igniting in the muffler of a car? (CP)
