Question-1 In the introduction of this experiment, there are several factors that are discussed as having an impact upon the rate of a reaction.
Pick one of these factors and come up with an original idea (not from the experiment or lecture) where the factor plays a role in the rate at which a chemical reaction occurs. Be sure to explain how and why your idea affects the rate of the reaction chosen.
For example: if you increase the surface area of a piece of coal by crushing it up, it will react with oxygen (burn) much more rapidly. This illustrates the relationship between surface area and reaction rate.
Question-2 There is a general rule of thumb that the rate of an observable chemical reaction doubles with every 10oC increase in temperature. How much would the rate of a chemical reaction change if the temperature were to increase by 40.0oC?
