Purpose: Chemistry related scientific software
Demonstration of the kinetics of series first order
reactions
Status of software: Freeware (although small donations are
always welcome)
__________________________________________________________
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.
