Part A

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:

$2A+3B3C+2D$

The concentrations of reactant A at three different time intervals are given. Use the following data to determine the average rate of

reaction in terms of the disappearance of reactant A between time $=0s$ and time $=20s.$

Express your answer in molar concentration per second to three significant figures.

You need to include the coefficient of reactant A while calculating the rate of reaction. You can make use of the

interactive activity to observe how the rate of reaction is expressed in terms of the "Disanpearance of reactants"
