The meaning when a smoggy day is considered “beyond index” should be mentioned and it should be stated whether a U.S. city ever recorded an AQI beyond index. Concept introduction: The AQI is an index for reporting daily air quality. It states about the cleanliness of air and if polluted; related health effects of concern. The AQI focusses on health effects which may be experienced within a few hours or days after breathing polluted air. AQI is calculated for five major air pollutants. They are, Ground level ozone Particulate matter Carbon monoxide Sulfur dioxide Nitrogen dioxide The scale of AQI ranges from 0 to 500 and higher the AQI value, higher the effects which can be caused due to air pollution. Word smog is derived from a combination of words, “smoke and fog”. Although the scale AQI scale in the USA is not applied to all other countries, the values can be according to the country.

When ozone levels in urban area reach unhealthy levels, residents are typically urged to avoid refuelingtheir cars during daylight hours. Explain how this might help to reduce smog formation?

determine how the rate at which ozone disappears is related to the rate at which oxygen appears in the 2O3(g) -> 3O2

Here is a graph of the pressure of ozone (03) in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below. atm 3.00+ 2.30- 200+ 1.938 150+ 1.00- 050- 0 500 1000 1500 seconds Is O3 being created or destroyed by the chemical reaction? If O3 is being created or destroyed, what is the rate at which it is being created or destroyed 1200 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If O3 is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 1200 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 2000 2500 created destroyed 3000 neither created nor destroyed 0 0 X 3 X [ロ･ロ
