Question

The rate of the reaction in terms of the "disappearance of reactant" includes the change in the concentration of the reactant, the time interval, and the coefficient of the reactant Consider the following reaction 2A + 3B rightarrow 3c + 2D The concentration of reactant A at their different time intervals given . Using following datas to determine the average rate of reaction interms of the disappearance of reactant A between time = 0s and time = 20s Express your answer in molar concentration per second to three significant figure

Explanation / Answer

The rate of reaciton is typically based on: 1 mol ;

in this case, we have 2,3,3,2 therefore, we must divide depending on the data given

if this is [A]. then we must divide by 2

The average rate of reaction in terms of A:

d[A]/dt = ([A]1 - [A]0) /(t1- t0)

d[A]/dt = (0.024-0.040)/(20-0)

d[A]/dt =-0.0008 M/s

rate of reaction is typically positive since it is "reaciton"

so

Rate based on A =0.0008 M/s
