Statement: 1 For the change occuring during roasting of sphalerite, the entropy change is negtive
Statement-2. Two different compounds of Zine are formed during roasting

A

Both I and II are correct and II is correct explanation of I

B

Both in and II are correct and li is not correct explanation of l

C

is true but ll is false

D

is false but II is true

Text Solution

Verified by Experts

The correct Answer is:
B
Statement-I `ZnS_((s))+3O_(2(g)) to ZnO_((s))+2SO_(2(g))` (correct)
`:.` Number of moles of gases products decreases so `Deltas=-ve`
Statement-II : During roasting two different compounds of Zn are formed.

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. Free energy change of Hg and Mg for the convertion to oxides the slope of DeltaG . T has been changed above the boiling points of the given metal because
