Mention the factors that affect the rate of a chemical reaction.
The rate of a chemical reaction depends upon the experimental conditions such as the concentration of reactants, temperature, and the presence of a catalyst.
In the case of gaseous reactants, pressure is also a factor that affects the rate of reaction. The dependence of the rate on the concentration of reactants is represented by the rate law, which is determined experimentally.
Explanation
The answer is derived directly from Section 3.2 'Factors Influencing Rate of a Reaction' and the Summary provided in the text. The textbook explicitly lists concentration of reactants (pressure in case of gases), temperature, and catalyst as the primary factors. It emphasizes that the rate law represents this dependence on concentration.
