At night, an equilibrium reaction between two different nitrogen compounds generates N₂O5 in the atmosphere, as represented

Question

At night, an equilibrium reaction between two different nitrogen compounds generates N₂O5 in the atmosphere, as represented below.
Reaction 1: NO3(g) + NO₂(g) N₂O5 (9)
K = 2.6 x 10-11
During the day, solar radiation is absorbed by NO3 (9), resulting in its decomposition. Which of the following best explains whether the equilibrium concentration of N₂O5 (g) in the atmosphere in the daytime is different from that in the nighttime, and why?
[N₂O5] will be higher during the day, because the decomposition of NO3(g) results in an increase in the rate of production of N₂O5 (g).
B
C
D
[N₂O5] will be higher during the day, because NO₂(g) will be in excess, leading to an increase in the rate of production of N₂O5 (9).
[N₂O5] will be higher at night, because the decomposition of NO3(g) in the daytime will result in an increase in the rate of consumption of N₂O5 (9) to reform NO₂(g).
N₂O5] will be about the same at nighttime and daytime, because the amount of NO₂(g) will not be changed and the equilibrium will not be affected.
