The Effect of Surface Area/ Particle Size on Reaction RateObjective: Investigate the effect of concentration on the rate of a reaction. Materials: 2 similar basin Detergent bar Stopwatch Detergent powder Procedure: Part A. Detergent bar 1. Fill one basin with 1 L of room temperature water. 2. Put the detergent bar into the basin of water. Record the time the detergent bar completely dissolves. Record data in Table 1. Part B: Detergent powder 1. Fill one basin with 1 L of room temperature water.2. Put 1 scoop of detergent powder into the basin of water. Record the time the detergent powder completely dissolves. Record the time the detergent powder completely dissolves.

Chemical reactions happen when reactants collide with one another. _____12. The rate of reaction is directly proportional to the number of collisions per second. _____13. The lower the temperature, the greater is the activation energy required for a reaction to occur. _____14. In lower concentration, molecules collide more often. _____15. For collisions to be effective, the reactants must be properly oriented.Image transcription textII. TRUE or FALSE. Write True if thestatement is true and False ifotherwise. 11.
