Regents Chemistry Exam January 2025 Question 18
18 Which term identifies a factor that affects the rate of a chemical reaction?
(1) decay mode (3) nuclear stability
(2) isotopic abundance (4) surface area
Solution:
Factors affecting the rate of reaction are :
Catalyst = speeds up reaction by lowering activation energy. Catalyst provides a new reaction pathway.
Concentration = increasing the concentration of reactants increases the rate of the reaction.
Surface area = increasing the surface area of the reactants increases the rate of the reaction.
Temperature = increasing the temperature of the reaction increases the rate of the reaction.
Choice 4 is the correct answer choice
