Which of the following statement is correct?a)Ecelland ΔrG of a c...

Ecell and rG are both important thermodynamic properties used to describe the behavior of electrochemical cells. Ecell represents the cell potential or electromotive force (EMF), which is a measure of the driving force for the cell reaction. On the other hand, rG (Gibbs free energy change) represents the thermodynamic driving force for a chemical reaction, including electrochemical reactions.

Ecell is an intensive property because it does not depend on the amount of substance present in the system. It is solely determined by the nature of the reactants and products involved in the cell reaction. Intensive properties are independent of the system's size or the amount of substance present. For example, the cell potential of a half-cell will remain the same regardless of whether it is combined with another half-cell to form a complete cell or if it is used in isolation.

On the other hand, rG is an extensive property because it depends on the amount of substance present in the system. The Gibbs free energy change is directly proportional to the quantity of reactants and products involved in the cell reaction. Extensive properties change with the size or amount of substance present. For example, if the number of moles of reactants and products in a cell reaction is doubled, the value of rG will also double.

Therefore, the correct statement is option C: Ecell is an intensive property while rG of a cell reaction is an extensive property. This means that the cell potential remains the same regardless of the scale of the reaction, while the Gibbs free energy change will vary depending on the amount of substance involved in the reaction.

In summary:
- Ecell (cell potential) is an intensive property, independent of the amount of substance.
- rG (Gibbs free energy change) is an extensive property, dependent on the amount of substance.
- Option C is correct because it correctly distinguishes between the intensive and extensive nature of Ecell and rG.

Which of the following statements is correct regarding Electrochemical cells?

Read the passage given below and answer the following questions:The objects which are non-superimposable on their mirror image (like a pair of hands) are said to be chiral and this property is known as chirality. Chiral molecules are optically active, while the objects, which are, superimposable on their mirror images are called achiral. These molecules are optically inactive. The above test of molecular chirality can be applied to organic molecules by constructing models and its mirror images or by drawing three dimensional structures and attempting to superimpose them in our minds. There are other aids, however, that can assist us in recognising chiral molecules. One such aid is the presence of a single asymmetric carbon atom.Q.

Read the passage given below and answer the following questions:The d block elements are the 40 elements contained in the four rows of ten columns (3-12) in the periodic table. As all the d block elements are metallic, the term d-block metals is synonymous. This set of d-block elements is also often identified as the transition metals, but sometimes the group 12 elements (zinc, cadmium, mercury) are excluded from the transition metals as the transition elements are defined as those with partly filled d or f shells in their compounds. Inclusion of the elements zinc, cadmium and mercury is necessary as some properties of the group 12 elements are appropriate logically to include with a discussion of transition metal chemistry. The term transition element or transition metal appeared to derive from early studies of periodicity such as the Mendeleev periodic table of the elements. His horizontal table of the elements was an attempt to group the elements together so that the chemistry of elements might be explained and predicted. In this table there are eight groups labeled I-VIII with each subdivided into A and B subgroups. Mendeleev recognized that certain properties of elements in Group VIII are related to those of some of the elements in Group VII and those at the start of the next row Group I. In that sense, these elements might be described as possessing properties transitional from one row of the table to the next.In the following questions, a statement of assertion followed by a statement of reason is given.
