Gamma rays
Explanation:
Every member of the electromagnetic radiation has commensurate amount of energy, wavelength and frequencies.
The electromagnetic waves with the shortest wavelengths and the highest frequencies are the gamma rays.
- Gamma rays also are the most energetic electromagnetic radiation.
- The short wavelength of gamma rays suggests that more waves passes with times.
- It's high frequency shows that a high amount of wave passes through a point at each passing of time.
- These factors combines to give its high energy. Energy of an electromagnetic radiation is a factor of its wavelength and frequency.
- Gamma rays are ionizing radiations which causes ionization of gas molecules.

Following reaction occurs in the given electrochemical system:
→ Fe +
Thus, under standard conditions
E(0) = E(0) Fe2+/Fe - E(0) Zn2+/Zn
where,
= standard reduction potential of Fe2+/Fe = -0.44 v
= standard reduction potential of Zn2+/Zn = -0.763 v
E(0) = 0.323 v
now, we know that, ΔG(0) =-nFE(0) ............... (1)
Also, Δ
On equating and rearranging equation 1 and 2, we get
K = exp(
)= exp (

There are 1.2 moles of KBr found in 3 Liters of 0.4 M solution.
<h3>HOW TO CALCULATE NUMBER OF MOLES?</h3>
The number of moles of a substance can be calculated by multiplying the molarity by the volume.
No. of moles = Molarity × volume
According to this question, 3L of a KBr solution are contained in a 0.4M.
no. of moles = 3L × 0.4M = 1.2moles
Therefore, there are 1.2 moles of KBr found in 3 Liters of 0.4 M solution.
