Because the reaction occurs between a metal and non metal
CL=2,8,7
C
The kinetic energy that the liberated electron has in eV based on the given values is :
10.28 eV.
<h3>Explanation:</h3>
- 1 eV is the kinetic energy gained by an electron or proton when acted upon by a 1 volt potential difference. E = QV is the formula for energy in terms of charge and potential difference.
A photoelectron's maximum kinetic energy is given by
Emax = hf - W
- where h is Plank's constant,
- f is the incident photon's frequency, and
- W denotes the metal surface's work function.
here given,
f = 3.62 x 10¹⁵ Hz
W = 4.70 eV
by recalling the equation for a photoelectron's maximum kinetic energy with given values,
Emax = hf - W
= ((4.14 × 10⁻¹⁵eV.s)(3.62 x 10¹⁵ Hz)) - (4.70 eV)
= 10.28 eV
As a result, we discovered that the maximum kinetic energy of electrons is 10.28eV.
