A form of “robustness” in which this quantity is constant across stoichiometric compatibility classes is exemplified by the E. coli glyoxylate bypass system. The time evolution of a vector of these quantities gives the dynamics of a chemical reaction network. Limit cycles in the space of these quantities arise in the Brusselator (-5[1])model, (15[1])which (-5[1])models the color changes of the BZ (15[1])reaction. (15[2]-5[1])To better model (15[1]-5[1])real electrolytes, Debye–Hückel (-5[1])theory scales these quantities by (*) activity (10[1]-5[1])coefficients. (10[2]-5[1])The time (10[1])derivative (10[2])of this quantity for a reaction (10[2])intermediate is assumed to be zero in the steady-state (10[3])approximation. (10[7])In rate laws for reactions (10[1])in solution, (10[1])species’ values for this quantity are raised to their stoichiometric (10[4])coefficients. (10[4])For 10 points, dilution (10[1])decreases what (10[1])quantity (10[3])whose unit (10[1])is moles (10[1])per (10[1])liter? ■END■ (10[7])
