Chemistry, The reaction between sodium Aim - The aim of this experiment was to find out the rate of a reaction at different temperatures. - We also wanted to find out the rate of the reaction at a different temperature in bigger or smaller surface areas. Prediction - My prediction is, by increasing the temperature a reaction will happen more quickly. The more heat - The Faster reaction and more collision. The lower the temperature - The slower the reaction and less collision. Time and Seconds Temp 1 2 3 Average 1/Time Cold 9(c 1.19 1.30 1.21 1.23 1/1.23=0.81300813 Room 22(c 5 4545 1.02 1.11 1.08 1.07 1/1.07=0.934579439 Warm 45(c 0.47 0.32 0.49 0.49 1/0.49=2.040816327 Hot 90(c 0.31 0.37 0.33 0.33 1/0.33=3.03030303 My Understanding Reactions occur at different speeds in different temperatures. I've learnt that if the temperature is high reactions will take place much more quickly and the particles will collide more often. The table and graphs prove my theory. The Calculator was used for calculating the average of the times that was recorded for the reactions to happen. The Beaker was used to mix the chemicals for...
