The rate of a chemical reaction is a function of the reactants and products, as well as of the temperature. One of the objectives of the kinetic study of a reaction is to determine the rate law. The rate law of a chemical reaction is the differential equation for the time rate of ...
The rate of a chemical reaction refers to the speed with which reactants are converted to products, the substances formed from the reaction. Collision theory explains that chemical reactions occur at different rates by proposing that in order for a reaction to proceed, there must be enough energ...

concentration of chemical A present and inversely proportional to the concentration of chemical B present.If the concentration of chemical B is increased by 100 percent,which of the following is closest to the percent change in the concentration of chemical A required to keep the reaction rate ...
一道GRE数学题,请详解The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and inversely proportional to the concentration of chemical B present.If the concentration of chemic
The rate of a certain chemical reaction is directly proportional to the square of the concentration of chemical A present and inversely proportional to the concentration of chemical B present. If the concentration of chemical B is increased by 100 percent, which of the following is closest to the...
Kinetics: The Rates of Reactions –Chemical kinetics – studies the reaction rates and mechanisms 16.1 Factors Affecting the Reaction Rate • Chemical nature of the reactants – each reaction has its own characteristic rate • Concentration – the reaction rate increases ...
