A student researches the use of a pressure cooker to cook foods quickly at temperatures above the normal boiling point of water. a. How could you use a particle model to describe why the pressure in a sealed pressure cooker increases as the water is heated.

Please write a body paragraph. Don't combine them I want two paragraphs.

b. What effect does the higher pressure have on the boiling point of water? Explain your reasoning.

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
