Which of the following factor(s) influence the rate of a chemical reaction?
Open in App
Solution
The correct options are
A Surface area of reactants
B Temperature
C Catalyst
D Concentration of reactants
The factors that influence the rate of chemical reaction are:
- Surface area of reactants: Powdered materials react more vigorously than solid materials. Moreover, reactivity increases if a material is in liquid or gaseous state.
- Temperature: It increases the kinetic energy of molecules and thus the rate of reaction increases.
- Catalyst: It does not take part in a reaction directly but increases the rate of a reaction.
- Concentration of reactants: With the increase in the concentration of the reactants the rate of the reaction increases.
