Statement 1: The reduction of a metal oxide is easier if the metal formed is in liquid state at the temperature of reduction.

Statement 2: The value of entropy change S of the reduction process is more on the negative side when the metal formed is in liquid state and the metal oxide being reduced is in solid state. Thus the value of Go becomes more on the negative side.

Explanation:

Statement 1: The reduction of a metal oxide involves the removal of oxygen from the metal oxide to produce the metal. This process requires energy in the form of heat. The reduction is easier if the metal formed is in a liquid state at the temperature of reduction because in the liquid state, the metal particles have greater mobility and can come into contact with the metal oxide more easily, enhancing the reaction rate. Therefore, Statement 1 is true.

Statement 2: The entropy change (ΔS) is a measure of the disorder or randomness of a system. In a reduction process, the entropy change is related to the physical states of the reactants and products. When the metal formed is in a liquid state and the metal oxide being reduced is in a solid state, the entropy change is more on the negative side. This is because the conversion of a solid into a liquid state is accompanied by an increase in entropy. On the other hand, the conversion of a solid metal oxide into a liquid metal and gaseous oxygen is accompanied by a decrease in entropy. As a result, the overall entropy change for the reduction process is negative.

The change in Gibbs free energy (ΔG) is related to the entropy change (ΔS) and the temperature (T) through the equation ΔG = ΔH - TΔS, where ΔH is the enthalpy change. When the value of ΔS is more on the negative side, the value of ΔG becomes more on the negative side. A more negative value of ΔG indicates a more favorable and spontaneous reaction. Therefore, Statement 2 is true.

Explanation of the relationship between Statement 1 and Statement 2: Statement 2 provides a correct explanation for Statement 1. The increased mobility of metal particles in the liquid state facilitates the reduction process, leading to a more negative entropy change and a more negative value of ΔG. Therefore, the reduction of a metal oxide is easier when the metal formed is in a liquid state, and the explanation for this lies in the more negative entropy change associated with this state. Hence, option A is the correct answer.

Similar Class 12 Doubts

Read the passage given below and answer the following questions:The amount of moisture that leather adsorbs or loses is determined by temperature, relative humidity, degree of porosity, and the size of the pores. Moisture has great practical significance because its amount affects the durability of leather, and in articles such as shoes, gloves and other garments, the comfort of the wearer. High moisture content accelerates deterioration and promotes mildew action. On the other hand, a minimum amount of moisture is required to keep leather properly lubricated and thus prevent cracking. The study indicates that adsorption of moisture by leather is a multi- molecular process and is accompanied by low enthalpies of adsorption. Further at 75-percent relative humidity, the adsorption is a function of surface area alone. Untanned hide and chrome- tanned leathers have the largest surface areas. The leathers tanned with vegetable tanning materials have smaller surface areas since they are composed of less hide substance and the capillaries are reduced to smaller diameters, in some cases probably completely filled by tanning materials. This process of tanning occurs due to mutual coagulation of positively charged hide with negatively charged tanning material. The result of the study indicated that untanned hide and chrome-tanned leather absorb the most water vapour.In these questions a statement of Assertion followed by a statement of Reason is given.
