Le Chatelier's Principle

[dinosaur93]

change in temperature

; endothermic

ok....I know that when you increase the temperature, the equilibrium will be shifted to the forward direction and more products will be formed to partially oppose the increase of heat absorbed (or [NO₂])by the reactant...and the reverse happens when you decrease the temperature.

Could someone pls help me put this is context in terms of Le Chatelier's Principle (with regards to equilibrium position)? Could someone give me like a modelled answer as to what I should say so that I would be able to obtain a full mark for this type of theory question? tnx..

because it's an endothermic reaction: reactants to products (forward) would decrease in temp and. conversely, products to reactants  (backward) would increase in temp [it's the opposite for exothermic reaction]

If it is in equilibrium and you increase the temperature, by Le Chatelier's Principle, the system will try to oppose the change by facouring the reaction that decreases the temperature. As this is an endothermic reaction, a net forward reaction will occur.

1-state the change
2- somehow mention le Chatelier's principle and state the system will 'partially oppose' the change
3- how will it oppose the change (e.g. favour reaction that will increase/decrease X)
4- a NET forward/backward reaction?

I think that should get you full marks...
