Question

Why does the rate of a reaction not remain constant throughout the reaction process?

pls answer fast

Answer 1

hi

here is your answer

a chemical reaction is change in which new substances are formed.

it includes evolution if heat and light and other new substances.

Reaction can be of two types depending upon the amount of heat released or absorbed:

1) Endothermic Reactions

heat is absorbed

2) Exothermic Reactions

heat is released

During a chemical reaction there is breaking and joining of bonds of atoms that leads to absorbing or releasing the heat energy,When you decrease the pressure, molecules don't hit each other as often and the rate of reaction decreases. Pressure is also related to concentration and volume. By decreasing the volume available to the molecules of gas, you are increasing the concentration of molecules in a specific space.

Answer 2

The rate of the reaction always depends upon the concentration of reactants/products per unit time.
