During winters, moisture condenses in the form of dew and can be seen on plant leaves and grass. The entropy of the system in such cases decreases as liquids possess lesser disorder as compared to gases. With reference to the second law, which statement in correct, for the above process?

A

The randomness of the universe decreases

B

The randomness of the surroundings decreases

C

Increase in randomness of surroundings equals the decrease in randomness of system.

D

The increase in randomness of the surroundings is greater as compared to the decrease in randomness of the system.

Which of the following statements is/are not correct? Adsorption is accompanied by decrease in enthalpy as well as decrease in entropy of the system. Gases, which can react strongly with adsorbent show chemisorption. When the value of the slope of the Freundlich isotherm is non-zero, adsorption is independent of pressure. Gold number of potato starch is 0.15

For a spontaneous reaction, the free energy change must be negative. DeltaG=DeltaH-TDeltaS is the enthalpy change during the reaction. T is absolute temperature, and AS is the change in entropy during the reaction. Consider a reaction such as the formation ofan oxide . M+O_(2) MO Dloxygen is used wp in the course of this reaction. Gases have a more random structure (less ordered) than liquid or solids consequently gases have a higher entropy than liquids and solids, in this reaction (entropy or randomness) decreases, hence is negative. Thus, the temperature is raised the DeltaS becomes more negative. Since, TDeltaS is subtracted in the equation, then SG becomes less negative. Thus, the free energy changes increases with the increase in temperature. The free energy changes that occur when one mole of common reactant in this case dioxygen) is we may e plotted graphically against temperature for a number of reactions of metals to their oxides. The following plot is called an Ellingham diagram for metal oxide. Understanding of Ellingham diagram is extremely important for the efficient extraction of metals. Which of the following elements can be prepared by heating the oxide above 400^(@)C ?
