r= (-dC/dt) = (kKC)/ (1+KC)
 In the L-H model, r is the reaction rate in mol/(m3 s), k is the kinetic rate constant, and K is the Langmuir-Hinshelwood constant, which is the ratio of the rate constants for adsorption and desorption (K = k1/k-1) and has units of inverse concentration. K = 1.2 * 10^-4 L/mol. Simplify the kinetic rate expression for the conditions in our experiment and solve the simplified differential equation analytically (e.g., by separation of variables and integration) to obtain an expression relating C to t. Rearrange your C vs. t equation to obtain a linearized expression (y = mx + b), where "y" and "x" are functions of experimentally measured or reported quantities (CMB, K, and t). What are "y" and "x"?
