The Effect Of Mass Of Catalyst On The Rate During The Creation Oxygen

Satisfactory Essays

Oxygen is one of the most important and widely distributed elements in the world, everyone breathes it every day. The exploration of oxygen is from thousands years ago; at the origin of human culture, on Mesopotamia plain, people started the earliest research about oxygen. “In 1772, oxygen was discovered by Joseph Priestley, in his diary, he wrote: ‘The feeling of it to my lungs was not sensibly different from that of common air, but I fancied that my breast felt peculiarly light and easy for some time afterwards, but maybe, in the future, who could assert oxygen won’t become a kind of luxury’”(Med., 2004). I decided to do the research on oxygen, an element that closely relates to everyone. This experiment will explore the effect of mass of catalyst MnO2 to the initial rate during the creation oxygen, in this paper, I will expound what is catalyst, the function of catalyst, and the way to make oxygen and measure initial rate. Experimental Question In this experiment, I explore the relationship between the mass of catalyst and the initial rates.
Preliminary Research “Kinetics is the study of the speed of a chemical reaction. Some chemical reactions are fast; others are slow. Sometimes chemists want to speed the slow ones up and slow the fast ones down.” (What character effect the speed of chemical reaction.2015)And catalyst is a kind of substance that increases the reaction rate and speeds up the reaction without using up themselves, chemically
