Can you attach the simulation?

Thanks.

If "A" is hydrogen, then your problem is the rate:

rA = stoichiometry * r

where stoichiometry = -3.

If "A" is CO2, your problem is your initial X (xH2 = 0.75 = 3 * 0.25 = 3 * xCO2)

I am not sure which is your A, so pick which of the two answers above is more appropriate.

I am also not sure how this relates to the factor 2 in your post, as I do not have a complete set of details for that.

On another note: to insert the greek letters in the text box, the easiest is to copy them from somewhere else, e.g. the character map. You can also just write the text somewhere else entirely and just paste the entire text. Note that there is a problem with rtf pasting in some versions though (fixed in the upcoming alpha).

Space-time Calculation Problem 2

Postby nrgeng » 14 April 2015, 15:23

Thanks for discovering my error with stoichiometry.
I sent a different simulation where coefficient "a" of a*A was 3 not 2.
My text application properly pastes text into my email client but not into COFE or alpha COFE. I have to paste to Word then to COFE. Too bad.

Text: check the next alpha, still working on it - I did fix it last week. If the problem persists, let me know.
