At night, an equilibrium reaction between two different nitrogen compounds generates N2O5N2O5 in the atmosphere, as represented below. Reaction 1: NO3(g)+NO2(g)⇄N2O5(g)   K=2.6×10−11NO3(g)+NO2(g)⇄N2O5(g)   K=2.6×10−11   During the day, solar radiation is absorbed by NO3(g)NO3(g), resulting in its decomposition. Which of the following best explains whether the equilibrium concentration of N2O5(g)N2O5(g) in the atmosphere in the daytime is different from that in the nighttime, and why? a.) [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.) [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(g) c.) [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(g) to reform NO3(g) d.) [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.

Question

At night, an equilibrium reaction between two different nitrogen compounds generates N2O5N2O5 in the atmosphere, as represented below.

Reaction 1: NO3(g)+NO2(g)⇄N2O5(g)   K=2.6×10−11NO3(g)+NO2(g)⇄N2O5(g)   K=2.6×10−11

 

During the day, solar radiation is absorbed by NO3(g)NO3(g), resulting in its decomposition. Which of the following best explains whether the equilibrium concentration of N2O5(g)N2O5(g) in the atmosphere in the daytime is different from that in the nighttime, and why?

a.) [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.) [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(g)

c.) [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(g) to reform NO3(g)

d.) [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.
