Photo chemical smog is a resultant of the reaction among Correct Answer NO<sub>2</sub>, O<sub>3</sub> and peroxy acetyl nitrate in the presence of Sunlight

Photochemical smog is a unique type of air pollution which is caused by reactions between sunlight and pollutants like hydrocarbons and nitrogen dioxide (NO and NO2). Other components of the photochemical smog include Ozone (O3) formaldehyde, peroxy benzoyl nitrate (PBzN), peroxy acetyl nitrate (PAN) and acrolein.

For a reaction, the extent of reaction equation is Ni = Nio + ϒVi is Where: Ni = Moles of species I present in the system after the reaction occurs Nio = Moles of species I present in the system when the reaction starts Vi = Stoichiometric coefficient for species i in the specified chemical reaction equation ϒ = Extent of reaction
Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is
For the reaction, A = X + Y, the respective concentrations are CA, CX and CY. The forward reaction rate constant is kf and the backward reaction rate constant is kb. Choose the correct statement from the following:
P. At equilibrium, kf CA > kB CxCy
Q. If the reaction is irreversible than, kb CXCY = 0
R. The backward reaction rate will essentially be first order, if the forward reaction rate is first order.
S. Activation energy for the first order forward reaction will be independent of temperature.

The question below consists of a set of labelled sentences. These sentences, when properly sequenced form a coherent paragraph. Select the most logical order of sentences from among the options.  P: Delhi’s air quality deteriorates with unfailing regularity, with large swathes of north India in the grip of suffocating smog, but the State governments that can make it easier for millions to breathe do not act with any sense of urgency.  Q: The smog that envelops the region is exacerbated by the burning of biomass in Punjab and Haryana, and the winter atmosphere is marked by weak ventilation.  R: It is unconscionable for governments, through indifference and inaction, to subject citizens to such toxic air, and cause extreme suffering especially among people with respiratory ailments and impaired lung function.  S: It has turned into a public health emergency in the capital, with the air quality index touching extremely hazardous levels in some parts, necessitating the closure of primary schools, has further lowered its standing.
