Light Phase consists of photochemical reactions which are carried out by two different photo systems, PS-I and PS-II. In the thylakoids, chlorophyll and other molecules are packed into units called photo system..

When pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight, smog is formed. This is a mixture of gases and since it is formed by photochemical reactions, it is called the photochemical smog. The word 'smog' is derived from the two words ..

Photochemical and Biosynthetic Phases - Light Phase consists of photochemical reactions which are carried out by two different photo systems, PS-I and PS-II. In the thylakoids, chlorophyll and other molecules are packed into units called photo systems. Each photosystem..

The average rate of reaction is calculated by determining the difference in [O 2 ] concentration over different intervals of time and dividing the difference by D ..

Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtained. Time/s 0 600 1200 1800 3000 4200 [O 2 ..

Stoichiometric Calculations Involving Reactions/Solutions - Most chemical reactions are carried out in solutions. It is therefore important to know how to express the concentration of the substance in its solution. Most common ways of expressing concentration of any so..
