Question

The rate of reaction indicates the speed at which the reactioncan occur. It can be expressed in terms of a change in theconcentration of reactants or products per unit of time:

The rate of reaction can be expressed either as a decrease in theconcentration of a reactant per unit of time or as an increase inthe concentration of a product per unit of time.

rate=concentrationchenge/time change

a) consider the follwing reaction:
2A+3B---->3C+2D
use the following data to determine the average rate of ractionbetween time0 s and 20s
time(s)0 20 40
[A](M) 0.0800 0.0480 0.0360

express answere in molar concentration persecond to threesignificant figures.

The rate of reation= ? M*s^-1
