Now i know! You mean,
Where are in Factors
the chapter 1 affecting rate
of reaction?!
story.....
It seem so,
what is this i'm not sure but
place? where are we
acctually?
.......
But in which It must be
factor are we? concentration
why there is so
much molecules
here and the
space is not
that big.
in order for a reaction to occur Hey !, Stop it. It Stop Pushing You are the
there must be collision between not anyone fault. me! one that push
other molecules....in order for
the place here me first!
effective collision to occur just too small and
1.molecules must collide with energy made us to collide
equal or greater than activation with others easily
energy.
2.molecules must collide with
correct orientation
In high concentration, what else can There is more ,
number of molecules effect the let me take you
per unit volume will reaction? somewhere else.
increase and cause the
frequancy collion and
effective collision
increase.At the end ,
the reaction will also
increase
This is a place During high temperture, the average
with high kinetic energy of molecules will increase
temperature and cause the number of molecules
increase . At the end, the frequency of
effective collision increase same goes
to the rate of reaction
what is this
place, why it’s
so hot here?
Hey, slow I can't slow down Whathoifwita'bsouat sure , let me
down ... you due to kinetic tecmopledrature? take you
running too
energy inside me is environment? somewhere
fust hight. This energy
cause me to run
faster
Let me show you how Oh no!!!
the low temperature I feel so cool
now.Please hurry up
affect us show me the reaction
of molecules here
As the temperature Right, average kinetic Oooo, Finally I know
decrease,the average energy is proportional that Reaction rate
kinetic energy of to the of molecules will
molecules also temperature.Hence,fr decrease in low
equency of effective temperature.
decrease.You see collision also decrease.
that?
This particles is so Sure, but we This small size
big . i can't move it need to move of particles
alone .. can you help are easier to
fast!
me? move.
What are Now I see ! The
they doing? smaller the size of
The smaller the size of reacting particle, The
particles, the more surface faster the rate of
area exposed for reaction and reaction.
cause the frequency of collison
per unit time and effective
collision increase .And the
result of rate of reaction will
increase
Wow, the sound is just Now let me show you how Catalyst is substance
like nice. Can you explain the last factor of that increases the rate
me more about catalyst reaction rate. It is
and how it be functional Catalyst of chemical reaction
to the rate of reaction? without itself being
Wow, it like consumed
catalyst provided
alternative
pathway to the
molecules
Now I’m start
regretting it
The presence of catalyst Thank you
will not affect the catalyst!
concentration of
product and reactant...
but i will increase the
reaction by lowering the
activation energy
