Question

Define the term rate of reaction in a simple way

Answer 1

Answer:

Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

OR

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically.

HOPE THIS HELPS YOU

I THINK IT DESERVES THE BRAINLIEST

ALSO DROP SOME THANKS

!!!!!!!!!!!!!!!EXPERT!!!!!!!!!!!!!!!!!!!!!!!GANESH!!!!!!!!!!!!!!!!!

I THINK MANY PEOPLE JUST THANK ME BUT NO BRAINLIEST ??

WHY??

ARE MY ANSWERS SO BAD HAA!!!

PLZ MARK BRAINLIEST I THINK THE ANSWER DESERVES IT

Answer 2

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. ... For most reactions, the rate decreases as the reaction proceeds.

Hope this helps you in simplest way!!!
