The breakdown of NO3 in the day leads to more consumption of N2O5 in the day hence its concentration is greater at night than in the day.
<h3>What is equilibrium constant?</h3>
The equilibrium constant is a number that shows how much reactants are converted to products in a reaction. It is often shown as capital letter K in English.
Given the situation described in the question, we know that the concentration of N205 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).

Michelle drove 50 miles per hour
Explanation:
300 miles divided by 6 hours equals 50 miles per hour.
Miles per hour basically just means

You can infer from the use of the word 'per' that you should divide the number of miles by the number of hours to get an average speed.
Similarly, to work out the number of miles driven you could say you travelled 50 miles per hour for 6 hours, so you would multiply 50mph x 6 hours to work the equation in reverse.
