GENERAL KNOWLEDGE

Detailed explanation-1: -The rate of reaction refers to the speed at which the products are formed from the reactants in a chemical reaction. It gives some insight into the time frame under which a reaction can be completed.

Detailed explanation-2: -The speed of a reaction is given by the reaction rate, a measure of how fast reactants are consumed and products are formed. The study of reaction rates is known as chemical kinetics. The central theory of kinetics is collision theory. The premise of this theory is simple: molecules have to collide to react.

Detailed explanation-3: -The fast reaction is defined as the reaction which takes a shorter time to complete. The fast reaction possesses a high rate of reaction. They possess smaller activation energy. The example of fast reactions are striking a match, burning of petrol in the car engine and so forth.

Detailed explanation-4: -If the phase of matter (solid, liquid, or gas) of the reactants results in more collisions, the reaction will be faster. Gas molecules move fast, so gases usually react faster than liquids. Liquids move faster than solids, so liquids react faster than solids.

Detailed explanation-5: -For the reaction N2O5(g)→2NO2(g)+21O2(g) the value of rate of disappearance of N2O5 is given as 6.25 × 10−3 mol L−1 S−1. As the temperature increases, rate of reaction increases because: In the following reaction 2H2O2(aq)→2H2O(l)+O2(g) rate of formation of O2 is 36 g. The reaction, More items
