Question

Consider the system
2N2O5(g) <----> 2N2O4(g) + O2(g) + heat
at equilibrium at 25C. If the temperature
were raised would the equilibrium be shifted to produce more N2O5 or more N2O4?

1. more N2O4
2. more N2O5
3. There would be no effect.
Just remember this about Le Chatelier's Principle. When a system at equilibrium is disturbed it will shift so as to undo what we've done to it.
So if we add heat the system will shift to use up the heat. Which way is that?
it would make more N2O5?
Right you are. Very good.
