Are Isothermal Processes Reversible?

Both isothermal and adiabatic processes sketched on a pV graph (discussed in The First Law of Thermodynamics) are reversible in principle because the system is always at an equilibrium state at any point of the processes and can go forward or backward along the given curves.

Is isothermal compression reversible?

The isothermal compression of the gas was performed in two ways, one irreversible and one reversible. The work done on the gas is positive because the gas is compressed; the surroundings do positive work on the gas. ... So the heat added to the compressed gas is negative, keeping the temperature constant.

What is isothermal reversible reaction?

Isothermal Irreversible Expansion

An isothermal process is a change in the system such that the temperature remains constant. In other words, in isothermal process ∆T = 0. ... Isothermal reversible change: q = -w = pex(Vf-Vi) Isothermal reversible change: q = -w = nRTln (Vf/Vi) = 2.303 nRT log (Vf/Vi)
