Introduction
The Reaction rate is the change in the concentration of a reactant or a product with time (M/s).
Pre-Requisites:
Average rate, instantaneous rate.
Activity:
The rusting of iron in the presence of air and moisture.
Real Life Question:
Why some reactions such as ionic reactions occur very fast but some reactions are very slow, for example rusting of iron?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Average Rate | The average rate is the change which is measured in concentrations at any given time period. |
| Instantaneous rate | The instantaneous rate is the change in concentration at any one particular time. |

Real life uses :
Low body temperatures slow down metabolism. In fact, warm-blooded animals regulate body temperature so that their biochemical reactions run at the correct rate.

What you learn in Theory:
The rate of a reaction can be defined as the change in concentration of a reactant or product in unit time.
What you learn in Practice:
Rate of a chemical reaction depends upon the rate of change in concentration of the reactants.
