Correct answer
A2NO2(g) 2NO(g) + O2(g)
Step-by-step explanation
From Boyle's law, we know when volume increase then pressure decreases, and to keep the pressure on original value the reaction should proceeds in the direction where the number of moles of gases increases.
In this reaction, only satisfy this.
2 NO2(g) 2 NO(g) + O2 (g)
ng = (2 + 1) 2 = 1
In this reaction, only satisfy this.
2 NO2(g) 2 NO(g) + O2 (g)
ng = (2 + 1) 2 = 1
