The rate of a reaction is how quickly the reaction goes to completion. If two reactions have the same amount of reactant, increasing the rate does not increase the amount of product produced, it simply reduces the time that it takes to make the product. Using the internet , research the four factors below that affect the rate of a chemical reaction. 1. Reactant concentration ( explained with details and add graphs to explain what you wrote for each one of them) 2. pressure ( explained with details and add graphs to explain what you wrote for each one of them) 3. Temperature ( explained with details and add graphs to explain what you wrote for each one of them) 4. Presence of a catalyst. ( explained with details and add graphs to explain what you wrote for each one of them) Your work should be written in complete sentences, and assume your audience is grade 11 chemistry students who do not understand this unit. Make sure all research is put into your own words!
