Question

which term refers to the speed at which reactants are converted into products?
○ reaction rate
○ activation energy
○ meta stable state
○ spontaneous reaction

Explanation:

To solve this, we analyze each option:

• Reaction rate: Defined as the speed at which reactants become products in a chemical reaction.
• Activation energy: The energy needed to start a reaction, not related to speed of conversion.
• Meta stable state: A state of a system that is stable but not in the lowest energy state, not about reaction speed.
• Spontaneous reaction: A reaction that occurs without external energy input, but this doesn't refer to the speed of conversion.

So the correct term is reaction rate.

Answer:

A. reaction rate
