What is Rate of a reaction

Text Solution

Verified by Experts

Rate of reaction : The [speed or velocity] of a reaction is the change in concentration of reactants or products per unit time.
Rate `(Deltax)/(Deltat)` Where, `Deltax` is the change in concentration,` Deltat` is the time interval.
The rate of reaction is always positive and it decreases as the reaction proceeds.
For the reaction,` R to P,` rate may be expressed as
a) Rate of disappearance of `R=("Decrease in concentration of R")/("Time taken for the decrease")=-(DeltaR)/(Deltat)`
b) Rate of appearance of `P=("Increase in concentration of R")/("Time taken for the increase")=+ (DeltaP )/(Deltat)`
