Which of the following thermodynamic processes is/are strictly irreversible? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

A process is reversible only if the driving force is infinitesimally greater than the opposing force. Slow extension of a spring and slow isothermal compression fit this limit. Spontaneous processes driven by finite gradients, such as heat transfer by radiation and unconstrained diffusion, are strictly irreversible.
