Factor affect chemical Reaction

 

The factors that affect chemical reactions are as follows:

1. Temperature: 

Increasing temperature increases the rate of chemical reaction. This is because temperature increases the kinetic energy of molecules, which increases the number of collisions between them and speeds up the reaction.

2. Pressure: 

Increasing pressure increases the rate of chemical reaction. This is because pressure increases the concentration of molecules, which increases the number of collisions between them and speeds up the reaction.

3. Concentration:

 Increasing concentration increases the rate of chemical reaction. This is because concentration increases the number of molecules, which increases the number of collisions between them and speeds up the reaction.

4. Catalyst

A catalyst speeds up the rate of chemical reaction. This is because a catalyst lowers the energy required for the reaction to occur, which speeds up the reaction.

5. Light 

Light can speed up the rate of chemical reaction. This is because light increases the energy of molecules, which increases the number of collisions between them and speeds up the reaction.

6. pH

pH can affect the rate of chemical reaction. This is because pH can change the structure of molecules, which changes the number of collisions between them and speeds up or slows down the reaction.

7. Ionic Strength

: Ionic strength can affect the rate of chemical reaction. This is because ionic strength can change the structure of molecules, which changes the number of collisions between them and speeds up or slows down the reaction.

These factors can change the rate of chemical reaction and affect the outcome of the reaction.

Example:

 The reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O) is affected by temperature, pressure, and concentration. Increasing temperature, pressure, and concentration of the reactants increases the rate of reaction and produces more water.
