Use the link above to 'run' the experiment. Go through each test in the suggested order and select the options from the list that best fit your observations. Each box should have two solutions when you complete this portion. To run a test click "Run Reaction". Use the drop down on the simulation to select a new variable and the choose to decrease. Next click "start over" to reset and choose the next condition. The sequence below matches your data table. Control Decrease Temperature Increase Temperature Decrease Concentration Increase Concentration Decrease Surface Area Increase Surface Area Add Catalyst

they both need two options for temperture concentration and surface area have decreased and increased
option, particles collide faster(steeper slope)
all a+b react to form c
control graph is directly proportional
some reactants remain only some product is formed
particles collide slower(lower slope)

To summarize the experiment and the observations based on the provided information, here are the suggested options for each condition along with appropriate observations:

  1. Control:

    • Observation 1: Control graph is directly proportional.
    • Observation 2: All A + B react to form C.
  2. Decrease Temperature:

    • Observation 1: Particles collide slower (lower slope).
    • Observation 2: Some reactants remain, only some product is formed.
  3. Increase Temperature:

    • Observation 1: Particles collide faster (steeper slope).
    • Observation 2: All A + B react to form C.
  4. Decrease Concentration:

    • Observation 1: Particles collide slower (lower slope).
    • Observation 2: Some reactants remain, only some product is formed.
  5. Increase Concentration:

    • Observation 1: Particles collide faster (steeper slope).
    • Observation 2: All A + B react to form C.
  6. Decrease Surface Area:

    • Observation 1: Particles collide slower (lower slope).
    • Observation 2: Some reactants remain, only some product is formed.
  7. Increase Surface Area:

    • Observation 1: Particles collide faster (steeper slope).
    • Observation 2: All A + B react to form C.
  8. Add Catalyst:

    • Observation 1: Particles collide faster (steeper slope).
    • Observation 2: All A + B react to form C.

This format allows you to clearly see the effects of various changes in conditions on the reaction rates and outcomes.
