-
- This application provides interactive help when the !Help
- application (or !Bubblehelp) is active, and requires Risc OS
- 3.1 or later.

- What this software does
- ~~~~~~~~~~~~~~~~~~~~~~~
- The concentrations of the three components A,B, and C are
- calculated for the system consisting of two sequential non
- reversible first order reactions during the specified time
- period, and the resulting concentrations can be displayed
- graphically.
-
- The simple reaction scheme is
-
- A ——> B ——> C
- __________________________________________________________
-
- Running the application
- ~~~~~~~~~~~~~~~~~~~~~~~
- As a fully RISC-OS compliant application it can be started
- from within the desktop by double clicking on the !A>B>C
- icon in a directory viewer, when it will be installed on the
- iconbar.
-
- On clicking with SELECT on the iconbar icon, a dialogue box
- will be opened, into which you can enter your chosen values
- for the rate constants for the first and second steps (k1
- and k2).
-
- You can also enter a time (in seconds) over which the
- reaction will be simulated. It is possible to change the
- number of increments used to span this time period, by
- simply clicking on the up and down arrow icons.
-
- There are three action buttons provided. The Close button
- will simply close the data entry window. Clear will clear
- all the writable icons to allow the entry of completely new
- parameters. Plot will open the graphical display.
-
- The algorithm used does not allow equal values of k1 and k2.
- The program will warn you if you attempt to use equal values
- of k1 and k2.
-
- Additional choices are also available from a menu.
-
- Use the on-line help once the application is running.
