Scheme of a chemical process consists of equ- ations ( marked with any symbolic identifier at the end of line) of chemical reactions of zero, first, second or third order (One at a line). Reagents and products should be presented by identifiers (6 symbols significance). '=', '+' used as delimiters. When reagents are put in ()brackets in a reaction, rate of the reaction is assumed to be uneffected by their concentrations, i.e. this does not alter reaction's order (though reagents will be consumed). When products of any reaction are of no inte- rest (importance) you may omit right part of equation (and '='). Calculator : Arithmetics + - + / ( ) Functions sqrt() exp() ln() log() and ^ for power Reagent's names and rate constants of current variant are permitted in expressions. Reag.'s name means its initial concentration. You should know that all data input is carried out through Calculator. Try this. Anamorphose : Default look_over mode is concentration/rate vs. time. You may change axes to any permitted (see Calculator) expressions. To refer to reagent's rate consumption use apostrophe (e.g. A'). To refer to certain concentration's/rate's value use indexation[]. Number and position of calculated points can be inquired about in a table-mode or by tur- ning switch "Smooth" off. NB!!! To avoid zero dividing in anamorphose expressions caused by null initial concentra- tions and so, set desired range of kinet. points to transform. Here are two reserved words - TIME (refe- rence to time) and LAST (the number of last point) - both upper-cased. Input : To enter a value start typing number or expres- sion (see "Calculator") at the chosen position. To edit previously inputted value press [Enter] ahead. End of input - [Enter], refusal - [Esc]. Any reagent's initial concentration or rate constant may be marked with [Ins] for the optimi- zation. Moreover, there is possibility (in calcu- lations, not in life) to prevent consumption of a reagent (make its concentration constant in calculations). Choose such reagent with [Del]. Chosen reagents (rate constants) are marked on the screen with '*' and 'C' respectively. All choices denied by repeated press of the keys. In TIME section are inputted : StepM - step of output. Results'll be written on a disc after every StepM seconds of virtual time. Total - total time of simulated process.
