WebChemical Kinetics 39 pRate law = k[A] [B]q where powers p and q are determined experimentally. Molecularity : The total number of reactants taking part in elementary chemical reaction is called molecularity. Order of reaction : The sum of powers to which the concentration terms are raised in a rate law expression is called order of reaction.
WebChemical kinetics: the area of chemistry dealing with the speeds or rates at which reactions occur. Rates are affected by several factors: • The concentrations of the reactants: Most chemical reactions proceed faster if the concentration of one or more of the reactants is increased. • The temperature at which a reaction occurs: The rates of ... WebChemical kinetics is the study of the speed or rate of a reaction under various conditions. Spontaneity ... Note that the rate is NOT constant but decreases with time.
