Question

explain the effect of concentration temperature and pressure on the rate of reaction​

Answer 1

Explanation:

When you increase the pressure, the molecules have less space in which they can move. That greater density of molecules increases the number of collisions. 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.

Answer 2

Answer:

Concentration. According to the collision theory of chemical reactions, concentration is an important factor because molecules must collide in order to react with each other. When the concentration of the reactants increases, the frequency of the molecules colliding increases, striking each other more frequently.
