Q. Consider the following statements regarding thermodynamic forces, fluxes, and entropy production in biological/open systems:

P. Thermodynamic forces represent the driving tendency for a process to occur.

Q. For any spontaneous, irreversible process, the entropy production rate satisfies 𝝈≥𝟎.

R. At thermodynamic equilibrium, thermodynamic fluxes become maximal while entropy production drops to zero.

S. A non-zero thermodynamic flux driven by its conjugate force leads to continuous entropy production in irreversible processes.
