Explain the term rate law
WebThe rate law for a chemical reaction can be determined using the method of initial rates, which involves measuring the initial reaction rate at several different initial reactant concentrations. WebIn chemistry, the rate law or rate equation for a chemical reaction is a mathematical equation that links the rate of forward reaction with the concentrations or pressures of the reactants and constant parameters (normally rate coefficients and partial reaction orders). [1] For many reactions, the initial rate is given by a power law such as

WebThe rates of chemical reaction are, in general, highly sensitive to temperature. Reaction rates increase as the temperature increases. The temperature dependence of the … WebThe rate law (also known as the rate equation) for a chemical reaction is an expression that provides a relationship between the rate of the reaction and the …
WebFeb 12, 2024 · Explain steady state and steady-state approximation. Derive a rate law when a mechanism is given but the rate determining step is not identified. Derive a general expression of the rate law using the steady-state approximation. Make appropriate assumptions so that the derived rate law agrees with the observed rate law. WebOne way is to use the method of initial rates. A rate law shows how a change in concentration affects the rate. The equation for a component A is #"rate" = k["A"]^m#, where #m# is the order of the reaction. Zero Order #"rate" = k["A"]^0 = k# The rate does not depend on the concentration. Whatever you do to the concentration, the rate will not ...
