Yeh that sounds more logical

Does the pressure of the reaction mixture decrease by 50% as the reaction proceeds in the forward direction?
I said yes but the answers didn't have the same opinion =T

Not sure if this is the reason, but I think it's because only the PARTIAL PRESSURES of each reactant change, not the net pressure of the reaction system.

Isnt the reason because the sulfur is in liquid state? ie. only the oxygen and SO2 affect the pressure, so as one is consumed, the other is produced?

fuck your right, collin said that the other day. That only gases affect pressure, and that liquids dont because no room to move or somthing.

[Pandemonium]

'no room to move' would actually mean less volume thus it would be affected.
it's more like the pressure change is negligible to volume change, thus concentrations are not affected.

..oh. *facepalm* thanks, it's obvious now you're pointed it out x.x

A student calibrated a solution calorimeter containing 100mL of water using electrical apparatus. The specific heat capacity of water is 4.18 J/C/g. Assuming that the student's measurements were reliable, which calibration factor is most likely for a well-insulated calorimeter?
A 240 J/K
B 480 J/K
C 960 J/K
D 1418 J/K

._.

lol, does this question remind anyone of a certain multi-choice question in a certain exam?
