In a reaction, the concentration of a reatant (A) changes from `0.200 "mol litre"^(-1) to 0.150 "mol litre"^(-1)` in 10 minutes. What is the average rate of reaction during this interval ?

Text Solution

Verified by Experts

`Delta[A]=[A]_("initial")`
`=[0.150-0.200]=0.050 "mole litre"^(-1)`
`Deltat=10` minutes
Average rate of reaction `=(-Delta[A])/(Deltat)=(-[-0.050])/(10)`
`=(0.050)/(10)=0.050 "mol litre"^(-1)"min"^(-1)`
