E-CodeLimiting reagent and theoretical yield — a TI-84 Plus CE program
LIMREAG is a TI-BASIC program for the TI-84 Plus CE. For aA + bB → cC from the grams and molar masses: moles of each reactant, which one is limiting, the theoretical yield in grams, the excess left over, and the percent yield if you give the actual yield.
What it asks for and what it shows
It asks for 9 values at its prompts. In the example below it shows MOL A, MOL B, YIELD G, LEFT G, % YIELD, LIMITING: B.
Example run
One of its oracle test cases: “2H2+O2→2H2O, O2 limiting, 65 g actual”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Input 1 | 2 |
| Input 2 | 1 |
| Input 3 | 2 |
| Input 4 | 2.016 |
| Input 5 | 10 |
| Input 6 | 31.998 |
| Input 7 | 64 |
| Input 8 | 18.015 |
| Input 9 | 65 |
| The screen shows | |
MOL A= | 4.96031746 |
MOL B= | 2.000125008 |
YIELD G= | 72.06450403 |
LEFT G= | 1.935495968 |
% YIELD= | 90.19697127 |
| Text | LIMITING: B |
How it's checked
6 test cases, each checked against an independent method. Replayed key by key on a virtual TI-84 Plus CE, they make 40 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “Limiting reagent and theoretical yield” (LIMREAG).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
