k is the rate constant. In this problem, we can substitute the pressure of the gas for the concentration. This would give us ln [A]t - ln 135 torr = -(6.8 x 10-4 s-1)(1420 s) Rearranging the equation, we get ln [A]t = ln 135 torr -( 6.8 x 10-4 s-1)(1420 s) Thi...

Figure 19.9.First order rate constant (k) for elimination is obtained from a plot of log compound concentration versus time. t½=0.693/k t½can also be calculated fromVdand CL using the expression t½=0.693×Vd/CL. Thus,PKhalf-life is determined byVdand CL. Increasing CL decreasest...
The rate constant is a function of contributions by the machine, the particles, and the froth. Machine The machine is responsible for production of bubble swarms and effecting bubble–particle collision. Recent work has related the machine “factor” to the BSAF. BSAF (Sb) is the rate at whi...
Smoluchowski equation with a sink term is widely used as a model of a rate process in a slowly relaxing environment. Two approximate solutions for the rate constant obtained for a steeply growing sink are tested numerically using an exponential sink. Both analytical solutions are in a good agreem...

Thedissociation rate constantallows the calculation of the time during which a reversible proteinase/inhibitor complex remains undissociatedin vivoin the presence of a dissociating agent (e.g.a biological substrate). Since complex dissociation is a first-order process, t1/2, the half-life time...
For a drug eliminated from blood according to first-order kinetics, the following equation can be used to calculate elimination rate constant:First-order slope = - K1 = - [Ln (C1)– Ln (C2)] / ΔT1Half-life (T1/2) = Ln 2 / K1 = 0.693 / K1 For a drug that obeys zero-ord...
the rate law is a differential equation. You can rewrite this and then integrate both sides to get a normal equation. Then use A(t) = 1/2 * A(0) and substitue this to find the expression for the half life and thus you can calculate k. ...
