understanding the role of a catalyst a
0:02
catalyst is a substance that speeds up a
0:04
chemical reaction without being consumed
0:06
or permanently altered in the process it
0:09
lowers the activation energy required
0:11
for a reaction to occur allowing it to
0:14
proceed more quickly and efficiently how
0:17
catalysts lower activation energy
0:19
activation energy is the energy needed
0:21
to start a chemical reaction catalysts
0:24
provide an alternative pathway with a
0:26
lower activation energy making it easier
0:28
for reactants to reach the energy
0:30
threshold needed to react thus
0:32
accelerating the reaction rate types of
0:35
catalysts homogeneous versus
0:37
heterogenous catalysts can be classified
0:40
as homogeneous or heterogeneous
0:43
homogeneous catalysts are in the same
0:45
phase as the reactants like liquids or
0:47
gases heterogeneous catalysts on the
0:50
other hand are in a different phase such
0:52
as solid catalysts used in reactions
0:54
involving gases or liquids catalysts in
0:58
biological reactions and enzymes in
1:01
living organisms catalysts are typically
1:03
proteins called enzymes enzymes speed up
1:06
biochemical reactions such as digestion
1:09
and cellular respiration by lowering the
1:11
activation energy needed for these
1:13
essential processes making them occur at
1:15
a faster rate the catalyst's role in
1:18
Industry catalysts are crucial in
1:21
industrial processes for instance they
1:23
are used in the production of chemicals
1:25
refining petroleum and synthesizing
1:28
Pharmaceuticals in these applications
1:30
catalysts help increase production rates
1:33
reduce energy consumption and lower
1:35
costs catalysis in everyday life
1:38
catalysts are present in various
1:40
everyday processes including the
1:42
catalytic converters and car exhaust
1:44
systems which help reduce harmful
1:46
emissions by speeding up the conversion
1:48
of toxic gases into less harmful
1:51
substances reversible nature of
1:53
catalysts one of the defining features
1:55
of a catalyst is that it is not consumed
1:57
in the reaction after the reaction it
2:00
can be recovered and reused which makes
2:02
catalysts highly efficient and cost
2:04
effective in both natural and Industrial
2:07
settings catalysts and reaction
2:09
specificity catalysts are often specific
2:12
to the reactions they accelerate for
2:14
example an enzyme may only catalyze a
2:16
particular substrate in a biological
2:19
process this specificity ensures that
2:22
the right reactions occur in the right
2:24
conditions from digestion to Cellular
2:26
functions the importance of catalysts in
2:28
green chemistry
2:30
catalysts are essential in green
2:32
chemistry aiming to make industrial
2:34
processes more environmentally friendly
2:36
by reducing the need for Harsh chemicals
2:38
and lowering energy requirements
2:40
catalysts help minimize waste making
2:43
reactions more sustainable and
2:44
eco-friendly
