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).
