Which of the following is NOT a secondary air pollutant? Correct Answer Nitric oxide

Secondary air pollutants are such pollutants whose formation occurs in the atmosphere due to chemical reactions. Nitric oxide is the only given option that is a primary air pollutant. The other options are all examples of secondary pollutants.

In the graph below, the concentration of a particular pollutant in a lake is plotted over (alternate) days of a month in winter (average temperature 10 °C) and a month in summer (average temperature 30 °C) Consider the following statements based on the data shown above: i) Over the given months, the difference between the maximum and the minimum pollutant concentrations is the same in both winter and summer. ii) There are at least four days in the winter month such that the pollutant concentration on those days are within 1 ppm of the pollutant concentrations on the corresponding days in the winter month. Which one of the following options is correct?
A pollutant P degrades according to first order kinetics. An aqueous stream containing P at 2 kmole/m3 and volumetric flow rate 1 m3/h requires a mixed flow reactor of volume V to bring down the pollutant level to 0.5 kmole/m3. The inlet concentration of the pollutant is now doubled and the volumetric flow rate is tripled. If the pollutant level is to be brought down to the same level of 0.5 kmole/m3, the volume of the mixed flow reactor should be increased by a factor of
