What is the kinetic energy of the emitted electrons when cesium is exposed to UV rays of frequency 1.0×1015Hz?
Anvisha [2.4K]
In order to emit electrons, the cesium will have to absorb photons. Each photon will knock out one electron by transferring its energy to the electron. Therefore, by the principle of energy conservation, the energy of the removed electron will be equal to the energy of the incident photon. That energy is calculated using Planck's equation:

E = hf

E = 6.63 x 10⁻³⁴ * 1 x 10¹⁵
E =  6.63 x 10⁻¹⁹ Joules

The electron will have 6.63 x 10⁻¹⁹ Joules of kinetic energy

Can someone easily explain to me how to do reaction rates?
iVinArrow [24]

Explanation:

Reaction rate is a measure of speed of a chemical reaction.

Usually, based on rates, reactions can be divided into two parts:

  • Slow reactions which usually takes a long time.
  • Fast reactions which takes place completely in seconds or microseconds.

Reaction rate can be defined as a change in the concentration of a reactant or product per unit time:

      The unit is  mol dm⁻³ s⁻¹

Reaction rate = \frac{change in concentration of a reactant and product}{time taken }

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
