A cell with the electrodes of the same metal and solution of the same compound but with a different solution concentration is given. The relationships between cell potential, Gibbs free energy change and w max and their use for the construction of above cell is to be stated. Concept introduction: Concentration difference leads to the spontaneous reaction in a concentration cell because a higher difference in concentration leads to positive cell potential and therefore, the change in Gibbs free energy comes out to be negative which means a spontaneous reaction. The Gibbs free energy change is the maximum work done therefore concentration difference will lead to the maximum work that can be obtained. To determine: The type of cell formed by the electrodes of the same metal and solutions of the same compound, but at different concentration; the relationships among w , Δ G , E , Q and the reason of spontaneous reaction taking place in the cell formed.

Concept introduction:
Concentration difference leads to the spontaneous reaction in a concentration cell because a higher difference in concentration leads to positive cell potential and therefore, the change in Gibbs free energy comes out to be negative which means a spontaneous reaction. The Gibbs free energy change is the maximum work done therefore concentration difference will lead to the maximum work that can be obtained.
To determine: The type of cell formed by the electrodes of the same metal and solutions of the same compound, but at different concentration; the relationships among
w,
ΔG,
E,
Q and the reason of spontaneous reaction taking place in the cell formed.
Indicate which option is false(A). Resistivity has a residual component and a thermal component.(B). In some materials resistivity increases with T and in others it decreases.(C). In insulating materials, resistivity is very low.
In ceramic materials, in relation to polymorphism, the same substance crystallizes differently when external conditions vary. Is this correct?
Indicate the type of bond that is considered to be a hydrogen bond.(A). Permanent dipole-dipole interaction between polar molecules.(B). Mixed ionic-covalent bond.(C). Principal interatomic bond(D). Van del Waals forces.
