Solved 7. What is the magnitude of the rate constant for the - Chegg

WebIn zero-order reactions, the rate law equation is Rate = k and the unit of rate constant in this case is, mol L − 1 s − 1. For first-order reactions, Rate = k [A]. The constant rate unit, in this case, is s − 1. On the other hand, second-order reactions have a rate law of, Rate = k [A] [B], and rate constant unit of. mol − 1 L s − 1. WebFor a given reaction under particular conditions, the magnitude of the first-order rate constant does not depend on whether a differential rate law or an integrated rate law is used. The differential rate law requires multiple experiments to determine reactant order; the integrated rate law needs only one experiment.

WebSuppose you are given the following figures that were extracted from the reaction of a certain substance. k (T) 1.0 x 10^2. [A] 0.002 M. [B] 0.001 M. m 2. n 0. So all we need to do here is plug in the value. Therefore, the rate constant rate is 4 x 10^-4 M/s. WebWhat is the magnitude of the rate constant for the reaction? A) 1.15 × 104 B) 4.6 C) 230 D) 115 E) 713 C. 230 Under constant conditions, the half-life of a first-order reaction ________. A) is the time necessary for the reactant concentration to drop to half its original value B) is constant C) can be calculated from the reaction rate constant

WebThe component of any net force that causes circular motion is called a centripetal force. When the net force is equal to the centripetal force, and its magnitude is constant, uniform circular motion results. The direction of a centripetal force is toward the center of rotation, the same as for centripetal acceleration. WebAnd now let’s see how this can be used for determining the activation energy or the rate constant of a reaction at a specific temperature. For example, The rate constant of a first-order reaction is 4.65 x 10-2 s-1 at 298 K. What is the rate constant at 380 K if the activation energy for the reaction is 70.4 kJ/mol?
