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 (-5[1])with respect to the “extent” (-5[1])of one of these processes. The quantity (10[1])“delta G-dagger” (10[1])appears (10[1])in the exponential (10[1])of Eyring’s theory of these (10[1])processes. (10[6])Plotting the (10[1])“coordinate” (10[3])of (10[1])these (10[2])processes (10[1])against (10[1])potential (10[1])energy (10[3])produces a bump whose (10[1])energy difference is necessary for “activation.” (10[5])For 10 points, (10[1])name these processes (10[1])whose rate constants (10[4]-5[1])are described (10[2])by the (10[1])Arrhenius equation.
