WebThe equation may be written as follows: (7.28) where ki is the intraparticle diffusion rate (mg/g min −1/2 ). If intraparticle diffusion is involved in the adsorption process, the plots of qt as a function of t0.5 should represent straight lines. The rate constants ki and Ci (mg/g) are evaluated from the slope and intercept of the regression line. WebNow, substituting these values in the integral form of the rate equation of second order reactions, we get: 1 [ R] 0 2 – 1 [ R] 0 = k t 1 / 2.

Diabetes mellitus is a growing global health burden affecting about 400 million people worldwide ().A person’s glycated hemoglobin fraction (HbA1c) reflects the average concentration of glucose in the blood (AG) over the past 2–3 months and is the gold standard measure for establishing risk for diabetes-related complications … A common form for the rate equation is a power law: The constant is called the rate constant. The exponents, which can be fractional, are called partial orders of reaction and their sum is the overall order of reaction. In a dilute solution, an elementary reaction (one having a single step with a single transition state) is empirically found to obey the law of mass action. This predicts that the rate depends only on t…
