Adding a catalyst to a chemical reaction results in

Chemistry
2 answers:
igor_vitrenko [27]3 years ago
7 0

Answer: Option (2) is the correct answer.

Explanation:

Activation energy is the minimum amount of energy required to start or initiate a chemical reaction.

Whereas a catalyst helps in increasing the energy of reactant molecules so that they can overcome activation energy barrier and actively participate in the reaction.

Hence, adding a catalyst to a chemical reaction results in a decrease in activation energy and an increase in the reaction rate.

How the fossil evidence helped you put the landmasses together (what was your process)
Otrada [13]

Explanation:

The idea behind using fossils to correlate two land masses was first put into limelight by a British geologist, Williams Smith.

According to the principle of fossil and fauna succession "fossils and fauna succeed one another in a define order".

This implies organisms evolve in predictable manner.

Since we know that certain types of organisms live within a period in time on the earth surface, we expect that such organisms would be fossilized in the geologic record and preserved.

  • Identify the fossil record in one part of the land mass. Log the rock types with the corresponding fossils in them.
  • On the other side, repeat the same process.
  • Look for unconformity surfaces where some part of the stratigraphic records might have been lost.
  • If the fossil records on one side corresponds with that on the other other side, it suggests that the land masses must have once been joined together.
  • The logic is that when the organism were on the same land mass, they thrived and lived together.
  • They became fossilized together till the lands separated.

The equilibrium constant of a reaction: A) is not related to the change in free energy of the reaction. B) is the same as the ma
Taya2010 [7]

Answer:) is related to the change in free energy of the reaction--d

Explanation:

For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as

 ΔG=ΔG⁰+RTlnQ  

where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient

Now when the system is in equilibrum,    ΔG⁰ which is the standard Gibb's Free Energy,is then  defined as

ΔG⁰=−RTlnK ,

where K is the equilibrium constant. because  ΔG becomes 0 and reaction quotient Q = K

The equilibrum constant   is related to the change in free energy of the reaction.

because when  ΔG is negative, the value of K is high which leads to a spontaneous. reaction

when   ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.

10095 m/sec to mile/ sec. 1 km = 0.6214 mile
Anarel [89]

Answer:

Explanation:

to convert any value in miles per second to meters per second, just multiply the value in miles per second by the conversion factor 1609.344. So, 10095 miles per second times 1609.344 is equal to 1.625 × 107 meters per second.

True or false stars will eventually burn out causing the universe become cold and dark
Art [367]

Answer:

False

Explanation:

At the end of the 1000 years, Satan will be released, defeated again, and then cast into the lake of fire (Revelation 20:7-10). Then, after a final judgment by God, the end of the world described in 2 Peter 3:10 occurs. The Bible tells us several things about this event.
