Reaction Rates- Rate of a Chemical Reaction - Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidati..

Generally, the rates of chemical reactions increase with increase in temperature. It is a common observation that perishable foods like milk, cooked vegetables decay more quickly in summers than in winter. Consider the chemical reaction: At 273 K, the h..

A chemical equilibrium involves two opposing reactions. If one of them is exothermic, the other must be endothermic. If a system at equilibrium is subjected to change in temperature, the equilibrium adjusts itself to counteract the effect of the applied change. Thus, ..

Example 5: Cyclopropane (C 3 H 6 ) at room temperature has a ring structure. When it is heated, the ring opens up and cyclopropane isomerizes to propylene. The reaction takes place in a first order manner. Therefore, the rate law for the reaction is, ..

) for the endothermic reactions. D H = H p - H r since (H p > H r ) D H = +ve For example: When a small quantity of ammonium chloride (NH 4 Cl) is dissolved in water in a test tube, the tube becomes colder than before. During this chemical reaction heat is absorbed from the surr..

>These reversible reactions never go to completion if performed in a closed container. For a reversible chemical reaction, an equilibrium state is attained when the rate at which a chemical reaction is proceeding in forward direction equals the rate..

According to the Le Chatelier's principle, when the temperature or heat supplied to a system at equilibrium is increased, the system should move in a direction so that the added heat is absorbed. Thus, an increase in the temperature of a chemical system at equilibrium, favours ..
