/sci/ - Science & Math

What kind of graphing software does /sci/ use? I'm trying to get a copy of Origin 8 because Excel makes shitty looking graphs that become marginally decent only after a lot of work.

Are there any respectable, free graphing programs out there?

one more thing ( pardon the bad notation here)

if we consider reactions that have a eq like:
A = C + D

CD/A = K

where A,B,C are concentrations ( mol / L)
it seems to be reasonable for me that if we double the volume, we have

(C/2)(D/2) / (A/2) = K /2 (half of K, not K)

but then i gather this is a mistake?

but i also read that lowering the pressure moves the equlibrium to the side with fewest molecules, which would be the "reactant" A.

So is K also dependent on the volume, or am i missing something?

>Validity of the model is established by comparing total areas obtained from this model to these same areas obtained from graphic method (less than +/- 0.4%).

smells numerical in here..

hey /sci. want to come play torment with us?
