Question

A theorem about these processes states that ones with “zero deficiency” have cyclic composition trajectories with positive composition only when they are weakly reversible. Stable periodic instances of these processes that exhibit “excitability” may self-organize in the presence of radiation. Ilya Prigogine (“pre-GO-zhin”) described how these processes are driven by a force called “affinity,” defined as a derivative with respect to the “extent” of one of these processes. The quantity “delta G-dagger” appears in the exponential of Eyring’s theory of these processes. (10[1])Plotting the (10[1])“coordinate” of these processes against potential energy produces a bump whose energy difference is necessary for “activation.” (10[1])For 10 points, name these processes whose rate constants are described by the Arrhenius equation. ■END■ (10[1])
