Active matter describes systems whose constituents convert energy from their surroundings into directed motion, such as bacteria or catalytic colloids. We present a thermodynamic law for suspensions of such active particles in the form of a remarkable direct link between their dynamics and thermodynamics: The irreversibility is a state function of the thermodynamic system parameters for low particle density, most importantly the swim pressure. Like in the famous fluctuation theorems of stochastic thermodynamics, irreversibility is a dynamical measure that quantifies the amount by which microscopic particle trajectories break time-reversal symmetry, without reference to the typically unobservable processes underlying self-propulsion.
