is the initial instantaneous rate larger or smaller than the average rate

The plot of concentration versus time is shown in below figure. The instantaneous rates were calculated at times 6.5 hours and 16.2 hour..

Example: Dehalogenation of trimethyl methyl bromide (CH 3 ) 3 CBr is given by the reaction. The following data were obtained. time/h [(CH3)3 CBr] x 10 - 2 M Instantaneous Rate Ms-1 0 10.39 3.15 8.96 6.20 7.76 Rate at time = 6.5 hours ..

Initial Rate Method - This method is used for reactions where more than one reactant species are involved. Initial rates of the reaction are determined by varying the concentration of only one reactant while keeping the concentrations of other reactants const..

. Average rate of a reaction does not represent the actual rate of a reaction at any instant of time. From the figures 6.1 and 6.2 it is clear that the rate of reaction actually decreases with time. This is because the rate of reaction depends on th..

But for having unique value of the reaction rate (independent of the concentration term chosen), we divide the rate of the reaction, defined with respect to any of the reactants or products by the number of moles involved in the reaction. Thus, for the above reaction, rateh..

Calculation of Average Rate of Reaction - Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtained. Time/s..

For this reaction, the increase in the concentration of acetic acid is determined by measuring the pH of the solution (sample). The concentration values obtained at different times are then plotted. From the graph of concentration versus time, the average rate and instantan..

The average annual rate of decrease in the population of a rare animal group is 4.5%. The initial population of the group is 2600. If the rate continues, estimate the population after 11 years. => 117 or 2483 or 1568 or 236..

Choose the exponential function with the initial value as 6, increasing at a rate of 48% per year. => S( t ) = (1.48) t or S( t ) = 6(1.48) t or S( t ) = 6(0.48) t or S( t ) = 6(1.16) t..

Rate of Heart Beat - The rhythmic contraction and relaxation of the heart to pump out and receive blood is called the heart beat. The rate of the heart beat varies from species to species. The smaller the animal, the higher is the metabolic rate and so greate..
