Define rate of reaction and explain the factors affecting rate of reaction |
|
Answer» Answer: The reaction rate or rate of reaction is the speed at which a chemical reaction TAKES place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.[1] Reaction rates can vary dramatically. For example, the oxidative rusting of IRON under Earth's atmosphere is a slow reaction that can take MANY years, but the combustion of cellulose in a FIRE is a reaction that takes place in fractions of a second. For most reactions, the rate decreases as the reaction proceeds. A reaction's rate can be determined by MEASURING the changes in concentration over time. |
