2. Learning Competencies:
• Describe how various factors influence the rate of a reaction. (STEM_GC11CK-IIIi-j-130),
• Explain the effect of temperature on the rate of a reaction,(STEM_GC11CK-IIII-J-135),
• Explain reactions qualitatively in terms of molecular collisions, (STEM-GC11CK-IIIi-j136),
• Explain activation energy and how a catalyst affects the reaction rate (STEM-GC11CK-
IIIij137), Cite and differentiate the types of catalysts, (STEM-GC11CK-IIIi-j138), (LAB)
• Determine the effect of various factors on the rate of reaction. (STEM-GC11CK-IIIi-j139)
3. What are examples of chemical reactions that
happen too quickly or too slowly?
4. Rate of reaction is a
measure of how fast a
reaction takes place. The
rate of a reaction is often
expressed as a change in
amount or concentration of
a substance (reactant or
product) per unit time.
Chemical kinetics is the
study of rates of reactions
and factors that affect them.
