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

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

Decreasing the concentration of N2O3
Heating the system
Adding a catalyst
Increasing the concentration of NO

Heating the system

Explanation:

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.

asking the goog might u get an answer

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
