From doing the investigation on rates of reaction I have found that the higher the temperature of a reaction, the quicker the reaction goes at.

From my results you can see that at 25c the reaction took 69 seconds compared to 45c, which took 43 seconds.

This agreed with my prediction, which was the higher, the temperature the quicker the reaction.

The scientific evidence which supports this is the temperature of a reaction is increased this would then increase the rate of reaction. A chemical that is heated will send energies of movement straight to the particles of the chemical.

When particles move faster this is known as more movement energy. When the particles move faster they will cause additional collisions.

This increased energy of the collisions means that more of the collisions are effective this then increases the reaction.

Evaluation.

together with my tie, which will need to be tucked into my shirt.
