define instantaneous 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 ..

Suppose a particle is moving in such a way that its average velocity, measured for a number of different time intervals, is not constant. This particle is said to move with variable velocity. Then, we must determine a velocity of the particle at any given instant of time, called the instantane..

. 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 the concentr..

When we travel in a vehicle the speed of the vehicle changes from time to time depending upon the conditions existing on the road. In such a situation, the speed is calculated by taking the ratio of the total distance traveled by the vehicle to the total time taken for the journey. This is called t..

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 instantaneous ..

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, ..

What is the instantaneous rate of change of f ( x ) = x + 3 at x = 9? => - 1 6 or - 6 or 1 6 or 6..

Find the instantaneous rate of change of f ( x ) = 3 x 2 + 4 x - 2 at x = 1. => 0 or - 10 or 10 or 5..

Find the instantaneous rate of change of f ( x ) = 96 x - 16 x 2 at x = 1. => 64 or 80 or - 64 or 0 or 1 64..
