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.

Decrease Temperature
Increase Temperature
Decrease Concentration
Increase Concentration
Decrease Surface Area
Increase Surface Area
Add Catalyst

I don’t see the simulation link or the exact multiple-choice options, so I’ll give the standard expected pair of answers for each condition (one describing the effect on reaction rate and one describing the reason/mechanism). If your options use different wording, map them to these ideas (increase/decrease/no change; more/fewer effective collisions, higher/lower kinetic energy, lower activation energy, etc.).
- Control
1) Rate = baseline (no change)
2) Baseline collision frequency/kinetic energy/activation energy (standard conditions)
- Decrease Temperature
1) Rate decreases
2) Fewer particles have energy ≥ Ea (lower kinetic energy) → fewer effective collisions
- Increase Temperature
1) Rate increases
2) More particles have energy ≥ Ea (higher kinetic energy) → more effective collisions
- Decrease Concentration
1) Rate decreases
2) Fewer reactant particles per volume → fewer collisions
- Increase Concentration
1) Rate increases
2) More reactant particles per volume → more collisions
- Decrease Surface Area
1) Rate decreases
2) Less exposed reactant surface → fewer collisions between reactant surfaces
- Increase Surface Area
1) Rate increases
2) More exposed reactant surface → more collisions
- Add Catalyst
1) Rate increases
2) Catalyst lowers activation energy (Ea) → a greater fraction of collisions are effective (no temperature change required)
If you paste the exact option list from the simulation, I can map each of these answers to those specific choices.
