Why does a catalyst not need to be replaced for a long time?

Chemistry
1 answer:
Juliette [100K]4 years ago
6 0
Because of the characteristic of catalyst. The catalyst is used to accelerate the reaction rate and will not participate the reaction itself. The catalyst can not be changed or consumed during the reaction. So it does not need to be replaced.

Is the following true or false every element in the periodic table follows the aufbau principle
gulaghasi [49]

Answer:

True

Explanation:

It is true that every element in the periodic table follows the Aufbau's principle.

The principle states that "the sublevels with lower energies are filled up before those with higher energies".

  • Sublevels do not fill up in numerical order.
  • This is true when writing the electronic configuration of all atoms on the periodic table.

Use the kinetic energy equation to explain why speed has a greater impact on kinetic energy than mass.​
Lerok [7]

Answer: <em>Hopefully this helps! sorry if not. :))</em>

<em></em>

<em>Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.</em>

A reaction has a forward rate constant of 2.3 × 106 s-1 and an equilibrium constant of 4.0 × 108. what is the rate constant for
avanturin [10]
Answer is: 5,75·10⁻¹.
Kf = 2,3·10⁶ 1/s.
K = 4,0·10⁸ 1/s.
Kr = ?
Kf - <span>forward rate constant.
K - </span><span>equilibrium constant.
Kr - </span><span>reverse rate constant.
</span>Since both Kf and Kr are constants at a given temperature, their ratio is also a constant that is equal to the equilibrium constant K.<span>
K = Kf/Kr.
Kr = Kf/K = </span>2,3·10⁶ 1/s ÷ 4,0·10⁸ 1/s = 5,75·10⁻¹.
