Name: Date: RATE OF REACTION WORKSHEET The following statements describe factors that affect the rate of chemical reactions. Use the word bank below to complete the statements. 1. T____ quickly they c_; This affects the energy of the particles and how increasing the of a system can lead to an increase in rate. It also affects the with which the particles collide and how the collisions are. The energy required for any reaction to take place is called the energy for that reaction. 2. C_; This is a measure of how crowded the particles are in a solution and the frequencies of . It changes the frequency of collision. 3. S a_; This is a measure of how much solid is exposed to reaction and therefore how many take place. It changes the frequency of collision. 4. The presence of a c_; These speed up a chemical reaction but is chemically. They work by lowering the activation ____ for the reaction.
