Can isobaric processes be reversible?

It is not necessary that all isobaric processes are reversible. Reversiblity is a very theoretical concept. Most reactions are irreversible. But, yes isobaric processes are mostly reversible because work done is proportional to volume and not pressure as in isobaric process pressure is constant.

What processes can be reversible?

Examples of Reversible Process

• extension of springs.
• slow adiabatic compression or expansion of gases.
• electrolysis (with no resistance in the electrolyte)
• the frictionless motion of solids.
• slow isothermal compression or expansion of gases.

What is the work done in isobaric reversible process?

An isobaric process occurs at constant pressure. Since the pressure is constant, the force exerted is constant and the work done is given as PΔV. An isobaric expansion of a gas requires heat transfer to keep the pressure constant.

Can an isothermal process be irreversible?

Isothermal expansion can surely be irreversible if you make it so. In fact, any process is usually at least a bit irreversible, and truly 100\% reversible processes are impossible.

What is irreversible and reversible process?

A reversible process is one in which both the system and its environment can return to exactly the states they were in by following the reverse path. An irreversible process is one in which the system and its environment cannot return together to exactly the states that they were in.

What is an isochoric process and isobaric process?

An isobaric process occurs at constant pressure. An isobaric expansion of a gas requires heat transfer to keep the pressure constant. An isochoric process is one in which the volume is held constant, meaning that the work done by the system will be zero.

How isothermal process is a reversible process?

Isothermal expansion continues as long as the applied force decreases and appropriate heat is added to keep pV = 2. The expansion is said to be internally reversible if the piston motion is sufficiently slow such that at each instant the gas temperature and pressure is uniform and conforms to the ideal gas law.

Are all isothermal processes internally reversible?

But the isolated statement “isothermal heat transfer processes are internally reversible” is false: they can be reversible or irreversible.

What are reversible changes class 6?

Reversible changes: The changes which can be brought back to its original form are known as reversible changes. For example, melting of wax and stretching of a rubber band. Irreversible changes: The changes in which the matter cannot be brought back to its original state are known as irreversible changes.

What is needed to reverse the process of spontaneous?

A process that is spontaneous in one direction is not spontaneous in the opposite direction. The direction of a spontaneous process can depend on temperature. To get the reverse process to occur, the water temperature must be lowered to 0°C. Chemical systems in equilibrium are reversible.

Can all changes be always reversed?

Nope…… only physical changes can be reversed,chemical changes are irreversible..

Are all isothermal and isobaric processes reversible?

All isothermal and adiabatic process when allowed to proceed slowly, are reversible, provided there is no loss of energy against any type of resistance. Friction, viscosity etc. Examples of some reversible processes are given below. Below are the locus of isothermal, isobaric, isochoric and adiabatic process.

What is the meaning of isochoric process?

An isochoric process, also called a constant-volume process, an isovolumetric process, or an isometric process, in a thermodynamic process during which the volume of the closed system undergoing such a process remains constant. An isochoric process is exemplified by the heating or the cooling of the contents of a sealed,…

Does entropy increase or decrease in an isochoric compression process?

The entropy would decrease If the process were an isothermal compression. An isochoric process is a process which takes place at constant volume (V = constant). The entropy change between states A and B is given by:

What is the difference between an adiabatic process and reversible process?

An adiabatic process is a process which takes place without transfer of heat (Q = 0). Since the gas does not exchange heat, we have: A reversible adiabatic process is also known as isentropic process, since the entropy of the system does not change. Knowledge is free, but servers are not.
