Chemistry rates of reaction gcse
WebCalculating rates of reaction. Reactions take place at different rates depending on the identities and conditions; Some are extremely slow e.g. rusting and others are extremely fast e.g. explosives; Rates of reaction can be measured either by how fast a reactant is used up or by how fast the product is made WebA substance that decreases the rate of a chemical reaction without being used up. 2. ...

Increasing the temperature of the reaction increases the speed at which particles move. There are more collision and the collisions have a higher energy. This increases the number of effective collisions.
