What is the rate of a chemical reaction?

Reaction rate, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Also asked, how can we calculate the rate of reaction on a graph?

The rate of reaction can be calculated from the gradient of a graph of amount of product against time of reaction:
  1. Draw a tangent to the curve (a straight line that represents the gradient at that point).
  2. Draw a vertical line and horizontal line to form a right-angled triangle with the line from step 1.

What are the units of the rate of a reaction?

For the purposes of rate equations and orders of reaction, the rate of a reaction is measured in terms of how fast the concentration of one of the reactants is falling. Its units are mol dm-3 s-1.
