Question

For which of the following systems at equilibrium at constant temperature will doubling the volume casue a shift to the right? H2+Cl2>2HCl, 2CO+O2>2CO2, PCl5>PCl3+Cl2, N2+3H2> 2NH3

aaronq · Answer

count the molecules of both sides of the equation, if you double the volume the eq will shift towards the side with more molecules.

anonymous · Answer

I'm working on that question as well

anonymous · Answer

How do you count the molecules?

anonymous · Answer

it got for an answer. H2+Cl2>2HCL

anonymous · Answer

In the PCl5<>PCl3+Cl2 I believe there is one molecule on the left and 2 on the right

anonymous · Answer

how did you get that one? I was getting D for an answer for some reason

anonymous · Answer

B not D because doesn't it have the most molecules on the right side forcing it to shift that way?

anonymous · Answer

Yeah you are correct. I was doing it wrong. You are right because you start out with one Molecule on D and end up with two after it shifts.

anonymous · Answer

Ok so did you get D? or is it B?

anonymous · Answer

D because if you look at the first person who commented. That is how I read it

anonymous · Answer

shoot! B I mean B!!!!

anonymous · Answer

Haha ok that's what I got!
