The Correct Option is D
Solution and Explanation
you can use the equation:
\(\Delta S=\frac{\Delta H}{T}\)
Given:
Enthalpy change (ΔH) = 6.0 kJ/mol = 6.0kJ/mol×1000J/kJ = 6000J/mol
Temperature (T) = 0°C = 273.15 K
Now, plug the values into the equation:
ΔS = \(\frac{6000\,J/mol}{273.15\,K}\)
ΔS ≈ 21.98 J/K/mol
So, the correct answer is (D): 21.98 J/K/mol
\(\Delta S=\frac{\Delta H}{T}\)
Given:
Enthalpy change (ΔH) = 6.0 kJ/mol = 6.0kJ/mol×1000J/kJ = 6000J/mol
Temperature (T) = 0°C = 273.15 K
Now, plug the values into the equation:
ΔS = \(\frac{6000\,J/mol}{273.15\,K}\)
ΔS ≈ 21.98 J/K/mol
So, the correct answer is (D): 21.98 J/K/mol

Concepts Used:
Radiation
Radiation is the energy or particles from a source that travels from one media to other. It travels through a medium after its emission from a source and is absorbed by matter.
Forms of Radiation:
- Particle Radiation includes the alpha (α), beta (β), and neutron radiations.
- Gravitational Radiation includes the radiation that takes the form of gravitational waves or as ripples in the curvature of space-time.
- Acoustic Radiation includes ultrasound, seismic and sound waves.
- Electromagnetic Radiation is inclusive of radio waves, gamma radiation (γ), x-rays, and visible light.
Types of Radiation:
- Ionizing Radiation - It carries more than 10 eV, that is enough to ionize atoms and molecules and break chemical bonds.
- Non-ionizing Radiation – It consists of alpha particles, beta particles, and gamma particles, whereas ionizing radiation consists of microwave radiation, infrared radiation and radio waves.
