ANSWER:Step 1 of 4
Reaction rate
The rate of a chemical reaction varies depending on the reactants, products and reaction conditions. The rate of a reaction, calculated as the change in concentration of reactants or products with time, is used to express the speed of a chemical reaction.
The rate is also calculated as the change in the number of moles of reactants and products with time. Therefore, the rate of a chemical reaction can be the rate of disappearance of reactants or the rate of products' appearance.
The reaction rate is calculated to find the optimum conditions for a chemical reaction. The conditions are adjusted such that a reaction occurs at a maximum rate with maximum product yield.
Since chemical reactions occur by the collision of reactant molecules, the rate of a chemical reaction depends on the frequency of collision and the energy of the colliding molecules.
