The rate of a reaction is a measure of how quickly a reactant is used up, or a product is formed.
There are different ways to determine the rate of a reaction. The method chosen usually depends on the reactants and products involved, and how easy it is to measure changes in them.
The mean rate of reaction can be calculated using either of these two equations:
m e a n
r a t e
o f
r e a c t i o n = q u a n t i t y
o f
r e a c t a n t
u s e d t i m e
t a k e n
m e a n
r a t e
o f
r e a c t i o n = q u a n t i t y
o f
p r o d u c t
f o r m e d t i m e
t a k e n
Measuring mass
The change in mass of a reactant or product can be followed during a reaction. This method is useful when carbon dioxide is a product which leaves the reaction container. It is not suitable for hydrogen and other gases with a small relative formula mass, Mr.
The units for rate are usually g/s or g/min.

I am water moleculeI have to first bear the heat of sun .Then the heat evaporates me into vapours I am send to the atmosphere with my brothersThen I have to form clouds Then precipitation or density of our brothers increasesWe keep increasingThen once a time comes when we are full We then condensed down to earthWe comes back in the form of rainThen either we are stored in some place or undergroundThen people collects us from different places like pond,river etc
Hey Lenny lately I’ve been having a rough time in the water cycle. It all started when I was chilling in my favorite location the “glaciars” and suddenly the sun turned me into liquid form. Next thing I know I am hurdling down a river straight into a massive lake. Personally this is my least favorite stage of the water cycle because of kids and bacteria that lurk in the water, very scary things. I didn’t stop at the lake very long, and instead sunk into the soil in a process called collection so I could become ground water. Underground reservoir’s are much more peaceful then lakes and I wanted to stay there. However I was forced up a water well pump shortly after and sent through a long tube. Me and couple of the friends I met on the way were all dispersed over a giant grass feild. Many molecules in the group were captured by the hostile plants but I escaped through the means of evaporation. Currently I have condensed into cloud form and I am roaming the skies looking for you, when you get this let me know and I’ll percipitate in your area! P.s I found this photo of us freezing over in the ice age lollll.
