Assertion: For adsorption G, H, S all have -ve values
Reason: Adsorption is a spontaneous exothermic process in which randomness decreases due to the force of attraction between adsorbent and adsorbate.
The correct answer is option 'C', which states that both the assertion and the reason are true, and the reason is a correct explanation of the assertion.
Explanation:
Adsorption: Adsorption is a phenomenon in which molecules or ions from a gaseous or liquid phase adhere to the surface of a solid substance. It occurs due to the attractive forces between the adsorbent (solid surface) and the adsorbate (molecules or ions).
Spontaneous Process: A spontaneous process is a process that occurs naturally without any external intervention. In a spontaneous process, the Gibbs free energy change (ΔG) is negative.
Exothermic Process: An exothermic process is a process that releases heat to the surroundings. It is characterized by a negative enthalpy change (ΔH).
Randomness and Entropy: Entropy (S) is a measure of the randomness or disorder of a system. In general, the entropy of a system increases when the system becomes more disordered.
Explanation of the Assertion:
The assertion states that for adsorption, G, H, and S all have negative values.
1. Gibbs Free Energy (ΔG): The Gibbs free energy change (ΔG) is related to the enthalpy change (ΔH) and entropy change (ΔS) through the equation ΔG = ΔH - TΔS, where T is the temperature in Kelvin. Since adsorption is a spontaneous process, ΔG must be negative. This implies that the sum of enthalpy and entropy terms is negative.
2. Enthalpy Change (ΔH): The reason states that adsorption is a spontaneous exothermic process. This means that adsorption releases heat to the surroundings, resulting in a negative enthalpy change (ΔH).
3. Entropy Change (ΔS): The reason also mentions that the randomness decreases during adsorption. A decrease in randomness corresponds to a negative entropy change (ΔS).
Explanation of the Reason:
The reason states that adsorption is a spontaneous exothermic process in which randomness decreases due to the force of attraction between the adsorbent and the adsorbate.
1. Spontaneous Exothermic Process: Adsorption is a spontaneous process, as mentioned earlier. It occurs naturally without any external intervention. Additionally, it is exothermic, meaning that heat is released during the process.
2. Force of Attraction: The reason mentions that the decrease in randomness during adsorption is due to the force of attraction between the adsorbent (solid surface) and the adsorbate (molecules or ions). This force of attraction is responsible for the molecules or ions adhering to the surface of the solid.
Conclusion: The assertion and reason are both true and are logically connected. Adsorption is a spontaneous exothermic process, and the decrease in randomness during adsorption
