Phases of reaction
« on: February 12, 2009, 09:19:55 PM »
I am working on some research for Silicon and have been able to figure out the phases of all of the isolation reactions but the following one.  Any help would be appreciated.  I am fairly certain that it is all gaseous, but am unsure what the Si would be.  Thank you in advance.

SiCl4 + 2H2 → Si + 4HCl

Well, the phase of any substance depends on two other things, the temperature and the pressure.  Do you have that info handy for this particular reaction?
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

There in lies my problem, as I do not know much other than it is a formula for isolation of Si.  I would imagine it would be near room temperature (which is why I made my prediction of gaseous in the previous post) but have limited information as to the specifics of the surroundings.  It seems to me that the HCl would form readily no matter what temperature and pressures happened to be, but I have been wrong before.

Solved the problem on my own, wasn't thinking clearly.  Thank you for your time in viewing.
