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 one for each
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)

It looks like you're conducting an experiment on the effects of various variables on the rate of reaction between two reactants, A and B, to form product C. Below, I've outlined the two options for each condition you mentioned (Control, Decrease Temperature, Increase Temperature, Decrease Concentration, Increase Concentration, Decrease Surface Area, Increase Surface Area, Add Catalyst) based on typical observations in reaction kinetics.

Experimental Conditions Overview

  1. Control

    • Observation: Graph is directly proportional (linear relationship between reactants and product).
    • Observation: All A + B react to form C.
  2. Decrease Temperature

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

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

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

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

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

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

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

Summary of Results

  • Control: Directly proportional graph; full reaction.
  • Decrease Temperature: Slower collisions; incomplete reaction.
  • Increase Temperature: Faster collisions; full reaction.
  • Decrease Concentration: Slower collisions; incomplete reaction.
  • Increase Concentration: Faster collisions; full reaction.
  • Decrease Surface Area: Slower collisions; incomplete reaction.
  • Increase Surface Area: Faster collisions; full reaction.
  • Add Catalyst: Faster collisions; full reaction.

Recommendation for Each Condition

When running each condition in the simulation, select the options above that best fit your observations. Make sure to click "Run Reaction" for each condition and then use the dropdown menu to adjust the variable before clicking "Start Over" to reset for the next test. This systematic approach will help you gather accurate data for your analysis.
