No, an isothermal process is not necessarily internally reversible.
For a process to be considered isothermal and reversible, it must occur at a constant temperature and be able to be reversed without any loss of energy.
The equation that relates the change in entropy (S) to the temperature (T), volume (V), and ideal gas constant (R) in a reversible isothermal process is S q / T.
The value of the polytropic exponent 'n' in a reversible polytropic process typically varies between 0 and ∞. However, common values for n are between 0 (isobaric process) and 1 (isothermal process) for ideal gases.
In thermodynamics, an isentropic process is a reversible and adiabatic process, meaning there is no heat exchange with the surroundings. An adiabatic process, on the other hand, does not necessarily have to be reversible, but it also involves no heat exchange with the surroundings.

No. All processes involving heat transfer are not reversible, since they result in an increase in entropy. Isothermal expansion implies heat transfer to maintain the system at a constant temperature. Normally an expanding gas would cool if there were no heat entering the system. Adiabatic processes involve no heat transfer and are reversible. The temperature can (and usually does) change during an adiabatic process.

An isobaric process is when pressure remains constant, while an isothermal process is when temperature remains constant in thermodynamics.
An isothermal PV diagram illustrates a thermodynamic process where the temperature remains constant.
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
An isothermal process in thermodynamics is when the temperature remains constant, while an isobaric process is when the pressure remains constant.
In an isothermal process, the internal energy of a system remains constant because the temperature does not change. This means that the relationship between internal energy and temperature is that they are directly proportional in an isothermal process.
This cannot be answered. This does not make any sense.
