Bps 319 Lecture 3 - Rates Of Processes
Questions And Answers
no, there is no "feedback" Does the dependent variable have an influence on the filling
rate?
Y = Y0 + K0(t) What is the equation for zero order fill?
Y = Y0 - K0(t) What is the equation for zero order empty?
linear For a zero order process, there is a ______ relationship between the dependent
variable and time
t = 0.5(Y0)/K0 What is the equation for the time for a zero order process to go to 50%
completion?
longer The greater the Y0, the ____ it takes to get to 50% completion
zero order emptying graph
zero order filling graph
, the rate changes in direct proportion with changes in the quantity being affected (dependent
variable) - so rate changes frequently What is the key characteristic of first order
processes?
emptying of a vessel by a hole in the bottom
growth of money in a savings account
almost all processes in ADME
Radioactive decay Examples of first order processes
the amount of water in the bath is the dependent variable because it is driving the rate of
emptying What is the dependent variable of the emptying bath example? (first order)
As volume decreases, height and emptying rate decrease How does the height of water in
the tub drive the first order process?
direct The dependent variable has a _____ influence on the rate of process
rate constant What does k stand for?
True T or F: The larger the rate constant (k), the greater the rate, and the faster the
emptying
Y = Y0e^-kt What is the equation for a first order process?
