According to les chattelier's principle, a system that is at equilibrium when disturbed will cause a change in the reaction's equilibrium by shifting the reaction's direction with the goal of minimizing the disturbance and therefore re -establish equilibrium.
00:21
That is by virtue of what we call as lesheteriae principle.
00:25
We are considering here a reaction that is equilibrium.
00:27
This reaction is between nita -amonia and oxygen gas to form nitric oxide, that's no, and water.
00:43
According to this balanced chemical equation, the endope change of this reaction is positive 906 kilojoules, indicating that this reaction is endothermic because the sign of the delta h is positive.
00:57
We want to know how will the following these turbines affect the equilibrium.
01:02
Concentration of nh3 if so we're going to find how nh3 concentration at equilibrium is affected by the following disturbances so first is when the when more no is added more and o is added and for letter b when you we remove h2o so we note that all of the species in this reaction are in gas state.
01:39
So for the first one, if we add a product such as no, the reaction will shift in the direction that will consume the added product.
01:48
And so the reaction shifts to the left.
01:55
So that means it goes backward since we add a react, we add a product that needs to be consumed.
02:03
And if shifts to the left or the reactant side, we say therefore that more reaction...
