Which is the lowest entropy?
SolidsSolids have the fewest microstates and thus the lowest entropy.
Liquids have more microstates (since the molecules can translate) and thus have a higher entropy.
When a substance is a gas it has many more microstates and thus have the highest entropy.
Mixing of substances will increase the entropy..
Are diamonds turning into graphite?
Diamond is the high-pressure phase that forms deep in the earth. Under normal conditions, diamond is metastable, meaning that it converts back to graphite when the process is initiated with sufficient energy. … It can switch its internal structure to a different order, thereby turning into graphite.
Which has more entropy diamond or graphite?
Graphite has more entropy than diamond because Graphite has free electrons(as free electrons are there energy can be distributed more) but diamond lack in free electrons. Hence, Graphite shows more entropy.
Which has least entropy graphite or diamond?
Diamond has least entropy due to its crystalline structure.
Is diamond to graphite spontaneous reaction?
According to thermodynamics, the reaction from diamond to graphite is spontaneous and favorable. However, because kinetics rather than thermodynamics is controlling this reaction, it occurs extremely slowly. So, diamond is kinetically stable, but thermodynamically unstable.
Which state of matter has the least entropy?
SolidsThe answer is (a) Solid. Solids have the lowest entropy value among the other states of matter since the molecules in solids are stationary.
At what temperature entropy of a substance is zero?
The Basic Law Specifically, the entropy of a pure crystalline substance at absolute zero temperature is zero. At zero temperature the system must be in a state with the minimum thermal energy.
Does a diamond last forever?
Diamonds do not last forever. Diamonds degrade to graphite, because graphite is a lower-energy configuration under typical conditions. In diamond, each carbon atom is bonded to four neighboring carbon atoms in a closely-packed three-dimensional grid. …
Why does diamond not conduct electricity but is very strong?
Diamond is very hard due to the strong covalent bonds and rigid tetrahedral 3d arrangement. It does not conduct electricity, as there are no electrons free to move and carry charge. … Carbon atoms have four unpaired electrons and can form four covalent bonds.
Why is standard entropy of graphite greater than diamond?
The entropy of graphite is larger than that of diamond because the diamond is in a compressed crystal lattice formation, which is much more ordered than the graphite structure. … Since the structure of a diamond is in a more ordered formation, it would be measured as having less entropy.
Why enthalpy of graphite is lower than diamond?
Greater entropy of graphite is related to its structure as graphite is less compact and rigid than diamond. for graphite is zero, but the Δ H f ∘ for diamond is 2 k J / m o l . That is because graphite is the standard state for carbon, not diamond.
Why does diamond spontaneously turn into graphite?
Diamonds do not last forever. Diamonds degrade to graphite, because graphite is a lower-energy configuration under typical conditions. … Diamond is therefore a metastable state. As is always the case in chemistry, energy must be inputted to break chemical bonds and allow new bonds to form.
