A higher concentration of molecules causes a faster chemical reaction. This is known as:

A. activation energy
B. chemical equilibrium
C. the law of mass action
D. metabolism



Answer :

Final answer:

Activation energy determines reaction rate; higher concentration and heat energy accelerate reactions.


Explanation:

Activation energy is the energy required for a chemical reaction to occur. A higher concentration of molecules leads to a faster reaction by increasing the likelihood of collisions. Heating a system provides the necessary heat energy to speed up reactions, increasing the frequency of collisions and facilitating the transition state.
