1. Consider the following system:
2NO(g) + O2(g) — 2NO2 (g)
Which of the following
would indicate whether equilibrium had been established?
And why?

A. [NO]> [02]
B. [NO]= 2[02]
C. [02]= 2[NO]
D. [NO] is constant

i think it is true since you can test the answer and can use observations to complete it.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.

i'm wiling to try and you : )
