These series of stages are known as the adoption process.
Normally when a product comes into the market the customer does not jump to it
the first time. Firstly the customer is always hesitant to go for the new
product. They try to learn in details everything about the product. After
learning about the product the customers give it a try to compare it with the
product they were using before. Then only the customer decides whether or not
to purchase the product, if it is better than the product they were using
previously.

The job of catalysts in chemical reactions is to make the reaction go faster by lowering the amount of energy needed to activate the reaction. If less energy is needed for the reaction to occur, then the reaction can go faster because a large energy build-up is not needed.
