The minimum combined kinetic energy reactant particles must possess in order for their collision to result in a reaction is call
lana66690 [7]

Answer: Activation energy

Explanation:

In a chemical reaction, the reactants contains particles which must collide in order for a reaction to occur. The rate of reaction depends on the frequency of effective collision between the reacting particles. Effective collision are those that result in reactions, which when they occur the colliding particles become activated with increased kinetic energy.

This energy must exceed a particular energy barrier for a particular reaction if the reaction must take place. This energy barrier that must be overcome before a reaction takes place is known as the ACTIVATION ENERGY.

To explain further, when two particles or molecules A and B come in contact with each other, for a reaction to take place, they must collide with a sufficient force to break the bond that exists between them. The minimum combined kinetic energy these reactant particles must possess in order for their collision to result in a reaction is called the activation energy.

When people respond to questions saying the answer is in an attached link, is it safe?
Mashcka [7]

Answer:

Personally, I believe it is unsafe. When people include a link in their answer, they are breaking the Brainly code, which states that a link to an unknown website is prohibited material.

Give the relation of energy (E) and frequency (v) as given by Planck. Calculate the frequency and energy of a photon of radiatio
andrew-mc [135]

<u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u><u>1</u>

\\ \sf\longmapsto E=hv

  • E denotes to Energy
  • h denotes to planks constant
  • v denotes to frequency.

<u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u><u>2</u>

  • Wavelength=3000Å

\boxed{\sf \lambda=\dfrac{c}{v}}

\\ \sf\longmapsto v=\dfrac{c}{\lambda}

\\ \sf\longmapsto v=\dfrac{3\times 10^8m/s}{3000\times 10^{-10}m}

\\ \sf\longmapsto v=0.001\times 10^{18}s^{-1}

\\ \sf\longmapsto v=1.0\times 10^{15}s^{-1}

Now

\\ \sf\longmapsto E=hv

\\ \sf\longmapsto E=6.626\times 10^{-34}Js\times 1.0\times 10^{15}s^{-1}

\\ \sf\longmapsto E=6.6\times 10^{-19}J
