Reaction Kinetic : 11.1 Reaction Rate

What is reaction rate?

how fast the concentration of reactant(or product) are change in a chemical reaction

How to expressing the reaction rate?

A + B

reaction rate = -d[A]/dt = d[B]/dt

The negative value of [A] indicates the decreasing amount of A which is the reactant

How to calculate the reaction rate ?

- by calculating the gradient of the following graph

How to differential the rate of reaction?
aA + bB → cC + dD

rate equation for the above reaction can be written as:

-1/a d[A]/dt = -1/b d[B]/dt = 1/c d[C]/dt = 1/d d[D]/dt
