rate of reaction is like rate of production at a factory

Categories: Comparisons

An example of a teaching analogy:

"A chemical reaction can be imagined as analogous to an automobile manufacturing plant. Raw materials like iron, plastic and glass are the reactants and cars are the finished product which roll off the assembly line at the other end of the factory. To measure the rate of this reaction, you could measure the rate at which a product is produced (e.g., #cars/day) or measure the rate at which a single reactant is used up (e.g., #tons of iron used up/day). This is the same idea as measuring the rate of a chemical reaction."
