Factors affecting rates of reaction

The rate of reaction depends on 4 things:

• Tempreture.
• The concentration of a solution or the pressure of gas.
• Surface Area-this changes depending on the size of the lumps of a solid.
• The presense of a catalyst

Increasing the tempreture increases the rate:

• When the tempreture is increased, the particles move faster.
• If they are moving faster, they are going to collide more frequently
• The faster they move the more energy they have, therfore the the collisions will ahve enough energy to make the reaction happen

Increasing the concentration or pressure increases the rate:

• If a soloution is made more concentrated, it means there are more particles knocking about in the…
