Question

What stress would shift the equilibrium position of the following system to the right?

N2O3(g) ⇌ NO(g) + NO2(g); ΔH is positive


Group of answer choices

Increasing the concentration of N2O3

Heating the system

Adding a catalyst

Decreasing the concentration of NO

Why the answer is not - Increasing the concentration of N2O3 -?

Answer 1

Heating the system

It's the correct answer on the test. I don't understand this very well, but adding a catalyst doesn't change the equilibrium, and increasing the concentration of NO would shift it to the left. Heating the system will shift it right in an endothermic equation, which this is.
