Measuring Speed of Reaction

The speed at which a chemical reaction proceeds can vary, and is called the rate of reaction. We will study about this in detail in this chapter.

I). Measuring Speed of Reaction:

The speed of reaction can be found by measuring these quantities at regular time intervals, when the chemical reaction is in progress.

• The volume of a gas produced by the reaction.
• The mass of the reactant that remains.

Either of the mentioned is measured, and a graph of that against time is plotted. The speed of reaction at any instant is measured by drawing a tangent against that point on the graph, and calculating its gradient.
