RATE OF REACTIONS. The reaction rate (rate of reaction) or speed of reaction for a reactant or product in a particular reaction is intuitively defined as how fast or slow a reaction takes place. For example‚ the oxidative rusting of iron under the atmosphere is a slow reaction that can take many years‚ but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second (right). Chemical kinetics is the part of physical chemistry that studies reaction rates. The concepts

Egil M 18.12 1 How Many Moles in my Name? Purpose The purpose of this experiment is to see how many moles there are in my name when writing with a chalk stick. I will attempt to see how little of the chalk I can use and still see my name clearly. Research question How do we calculate moles? How might we manipulate the variables? Theory So if I am going to find out how many moles there are in my name I have to know how to work it out. The «Mole» is a unit of measurement‚ just like a dozen or

A Mole is a unit‚ or have you heard. Containing six times ten to the twenty- Third‚ That’s a six with Twenty-three zeros at the end‚ Much too big a Number to Comprehend Say you had a Mole of Dimes to Distribute round the world‚ Give to each of the five billion grownups‚ Boys and girls‚ There wouldn’t be a single soul down and out of luck‚ Cause everybody in the world would get a trillion bucks. Or say you had a mole of construction paper and Stacked it towards Space Construction
