Chemistry Question

[Ridenour]

This one's for all you chem-smart guys out there.

I need to know; when referring to equillibriums in general:

What happens when the temperature of the reaction is raised?

What happens when the temperature of the reaction is lowered?

I guess I'm referring to a balanced reaction: - I need to know will more substances move to the left or right; or vise versa.

Thanks guys.

If the temp goes up, so does the rate of reaction. If temp goes down, so does the rate of reaction. Is that what you wanted to know?

What about the chem-smart girls ?

ec437 is right...raising the temp will favor the products (right).

LoL O I almost forgot...

Ok, that makes sense. You both are right thanks.

Hey sunfire; I see you're from San Diego. You better watch out; my friend's just about to get out of Marine basic training down there, and he's gonna be stationed down there. I wouldn't frequent any bars in that city for the next 4 years - he talked 24/7 before he left about the giant "macking spree" he was gonna go run at all the local bars on all the cali chicks

High temps = faster moving molecules = faster reactions

What kinda chemistry class are you in that you didn't know that?

[Ridenour]

Well I understand that, but I'm trying to figuire out what's going to happen to the "equillibrium point" - I suppose it's going to move to the left since the bulk of the equation will move to the right (products) due to more reaction.

All too familiar with the military personnel in bars. Actually it's become a rule to look but don't touch !

Anyway...not been in too many bars lately...broke boyfriended graduate student in last months, trying to write thesis, get a job (and fix cranky car). Plus, surf is back up and basically free and much more healthy!

Good Luck to your friend...it's definitely a (expensive) candy store down here!

Check your textbooks

We can't tell you if it moves left or right because we don't know what's reacting and what the heat change is, but remember that whatever happens the reaction will move the opposite way to counter it.

[CA_sunfire]

If the reaction is endothermic (meaning must add heat in for the reaction to go), then adding heat will favor the products. The heat of the reaction or change in enthalphy (H) is often positive.

Most reactions that are exothermic (or give off heat, enthalpy is negative) are spontaneous and irreversible so it's not a matter of what side is favored. Adding heat of course won't favor the products.

So whatcha cooking? Or is this just chemistry class?

Once a stable temperature (higher or lower) is established you have a Dynamic Equilibrium, once anything distrubs that, so is the rate at which the reaction is occuring (or the products and reactiants). The answer has already been said.

If no more products (same or differant) are added, you get the same thing, since you're only affecting the environment, the rate of production is increased with temperature rise, and decreased with temperature decrease.


If the reaction is not reverasble, it's not an equilibrium.

do yer own homework. It's in yer book somewhere.
