Catalysts increase reaction rates by lowering the activation energy of a reaction.
Setler [38]
The answer is true, catalysts increase rates by lowering the activation energy of a reaction. Catalysts lower the reaction energy and so the reaction occurs faster. Enzymes perform the role of biological catalysts. Most metabolic pathways of the body are controlled by enzymes. Enzymes by classification are proteins. <span />

If a 750 mL of a gas at a pressure of 100.7 kPa has a decrease of pressure to 99.8 kPa, what is the new volume? Show work
SVEN [57.7K]

Explanation:

P1V1 = P2V2

(100.7 kPa)(0.75 L) = (99.8 kPa)V2

V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)

= 0.757 L

In the example, the final kinetic energy is determined to be ___________ because at the peak height, the ball instantaneously st
alina1380 [7]

TLDR: The kinetic energy is determined to be zero.

Kinetic energy is energy of motion; when an object is moving (i.e. it has speed or velocity), it has some amount of kinetic energy. The equation itself looks like so:

KE=1/2(m)(v)^2,

where "m" represents the mass of the object and "v" represents the objects speed or velocity. In this example, the ball has stopped, meaning it has no speed/velocity. This means that the final kinetic energy is determined to be zero or none, due to the lack of motion. Mathematically, you can see this by substituting "0" in for "v" (the ball is stopped):

KE=1/2(m)(v)^2

KE=1/2(m)(0)^2

KE=1/2(m)*0

KE=1/2*0

KE=0 J,

or zero kinetic energy.

Hope this helps! :)
