he stated that when a chemical systems equilibrium is is disturbed, the system always appears to react in direction that opposes the change until new equilibrium what does that mean? example?
Ok we'll uses a simple reaction to explain I like to use 2h2 + o2 <-> 2h2o
If we add either of the reactants(h2 or o2) the reaction will try to rebalance itself but making more product until equilibrium is reached
One the other hand if h2o is added the reaction will shift in the direction of the reactants until equilibrium is reached
Additionally if pressure were to increase(decrease in volume) the reaction will shift to the side with less moles which is the product side 3 vs 2 mols and visa versa is pressure were to decrease the reaction will shill to the side with more moles the left side (reactants)
I hope this helps
ok makes sense now! one more question, when you add or remove energy so endo or exo which one is producing products and which reactants?
my text book is kinda confusing as it contradicts itself.... @zoomiemoo
This confused me too I thought I was never going to get it
when you think about it exothermic reactions make energy energy a->b+heat. If you add heat the reaction will try to counteract it by shifting to the reactants so not as much heat is lost in the first place
does that make sense?
ok so that's what I thought, but for one example.....
|dw:1432790394811:dw| it said it shifted right so more products favoured but that didnt make sense....
is there a difference in terms when talking about removing vs releasing absorbing vs adding?
The terms usually mean the same thing. Is it possible to take a picture of your textbook and post it
mhhmm ill even outline where its contradicting itself just give me a second
unless it said it absorbed energy 'from' the equation then it would mean that they are taking energy away from the reaction
could you explain that? what does from the equation mean?
Think of a sponge that absorbs heat. It is put into the reaction to absorb heat from the reaction. This means that the heat is reduced from the system
oh so your saying the surrounding is absorbing heat but system is releasing right?
ya. Is that what the question said?
