In a rate law the k term corresponds to the:
WebSep 28, 2015 · Rate laws or rate equations are mathematical expressions that describe the relationship between the rate of a chemical reaction and the concentration of its reactants. In general, a rate law (or differential rate law, as it is sometimes called) takes this form: … WebApr 11, 2024 · A zero-order reaction means that the rate of the reaction is independent of the concentration of the reactants. Rate Constant Since rate constant is given by Rate = k [ A] x [ B] y So, k = R a t e [ A] x [ B] y The units are calculated by the following equation: k = ( M ⋅ s − 1) × ( M − n) = M ( 1 − n) ⋅ s − 1.
In a rate law the k term corresponds to the:

WebFollowing are two statements pertaining to the reaction 2A + B → 2C, for which the rate law is rate = k [A] [B]. Identify which statement is true and which is false, and explain your reasoning. (a) The value of k is independent of the initial concentrations [A] 0 and [B] 0. (b) The unit of the rate constant for this reaction can be expressed ... WebThe integrated rate law can be written in the form of a straight line as: Therefore, if the reaction is second order, a plot of versus t will produce a straight line with a slope that …
WebGiven rate law equation: rate = k [B] 2 Power of [B] is 2. So the order of this reaction = 2 That is, this is a second order reaction. For a second order reaction, integrated rate law equation is given by: 1/ [B] = kt Therefore, slope of a plot between 1/ [B] vs time will be equal to the rate constant (k). View the full answer Step 2/3 Step 3/3 WebFor example, the rate law for step 1 is rate=k [NO2]2rate=k [NO2]2 The exponent "2" is used because the reaction involves two NO2NO2 molecules. The rate law for step 2 is rate=k [NO3]1 [CO]1=k [NO3] [CO]rate=k [NO3]1 [CO]1=k [NO3] [CO] because the reaction involves only one molecule of each reactant the exponents are omitted.
