Whenever there is an infection or tissue injury, it results in redness, swelling, pain and production of heat and may result in fever. Such a manifestation is localised and is known as inflammatory response . Inflammation is characterised by 4 fundamental symptoms: redness , pain , h..

As noted earlier, the rate of reaction also depends on p, the fraction of collisions that occur with proper orientation. This factor is independent of temperature. Why proper orientation of the reactant molecule is important can be understood from the figure. fig 6.13 - Importance of molecular orie..

. f = e - E a / R T (22) The effect of this factor on k can be best explained with an example. Examples 13: The reaction of nitric oxide (NO) with chlorine (Cl 2 ) is believed to occur in a single step. The activation energy for the reaction is 8.5 x 10 4 J / mol. At 298 K the fraction of collision..

As we know that we cannot live without air even for a single minute. We live in a vast ocean of air, which extends upwards for over 1000 km. Apart from providing us air to breathe, this blanket of air traps the sun's heat that is essential for life on t..

Humans can only live about five minutes without air. Dry air is generally a homogeneous mixture (solution) of nitrogen gas (78%), oxygen gas (21%), and traces of other gases. Some of the other gases are waste products of human activities and are known as air..

Accidents - Large area of forest catches wild fire accidentally. If not controlled in time by proper methods, fire grows out of proportion. In the last 5 years two major wild fires (in USA and Malaysia) are recorded. Each of them has sent an estimated 1.5 million tons of CO 2 to atmosphere. Over ye..

The various categories of air pollutants and their harmful effects are summarised in the given table: Pollutant Source/Cause Effect Carbon monoxide Automobile exhaust, photochemical reactions in the atmosphere, biological oxidation by marine organisms, etc. Affects the respi..

>All reactions, whether burning of magnesium (or any metal) or hydrocarbons (like wax) follow the law of conservation of mass. The apparent increase or decrease in mass is due the unaccounted gases that are taken or given out. Respiration is the burning of food in the living cells. The product..
