Which equilibrium system least favors the formation of products?
2hgo(s) 2hg(l) + o2(g) keq = 1.2 x 10-22
ch3cooh(aq) + h2o(l) h3o+(aq) + ch3coo-(aq) keq = 1.8 x 10-5
2no(g) + o2(g) 2no2(g) keq = 6.5 x 105
2(g) + cl2(g) 2hcl(g) keq = 1.8 x 1033

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
