Which term best describes the measure of the increase in the concentration of a product per unit time?

activation energy, kinectics, reaction reaction rate, reaction time

im stuck i think its activation energy can someone confirm this or let me know what is the correct anwser?

I've answered this before but perhaps not for you. The reaction rate is a measure of the change in concentration of a substance per unit time. Activation energy is the energy that must be attained before a reaction will start although thermodynamics tells us that the reaction is spontaneous.

The correct answer is "reaction rate." The reaction rate is indeed the term that best describes the measure of the increase in the concentration of a product per unit time.

If you want to confirm this information or explore further, you can consult a reliable chemistry textbook or conduct an online search using reputable sources. These sources should provide you with definitions and explanations of the terms related to chemical reactions, such as activation energy, kinetics, reaction rate, and reaction time.
