Software for RISC OS

This is a demonstration of the kinetics of series first order reactions. 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

A>B>C is now 26/32-bit neutral and runs on Select 4.33 and on the Iyonix.

MolWeight calculates from a molecular formula the molecular weight, and also the mass of the compound corresponding to a selected number of millimoles. The percentage elemental composition can be displayed, and the user may also define their own groups for use in calculations. Formulae are entered in a way as near to the conventional method of writing formulae as is consistent with the standard WIMP interface.

MolWeight is now 26/32-bit neutral and runs on Select 4.33 and on the Iyonix.
