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.

Question

for temperture concentration and surface area have decreased and increased one for each
not all product collide
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)

Answer 1

Sure! Below is a structured response that outlines how to run the experiment with the observations for each test condition you mentioned:

Experiment Setup

1. Control

   • Observation: The graph is directly proportional (linear relationship) as the reaction proceeds smoothly with all reactants converting to products efficiently.

2. Decrease Temperature

   • Options Selected:
     • Particles collide slower (lower slope)
     • Some reactants remain; only some product is formed.

3. Increase Temperature

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

4. Decrease Concentration

   • Options Selected:
     • Particles collide slower (lower slope)
     • Some reactants remain; only some product is formed.

5. Increase Concentration

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

6. Decrease Surface Area

   • Options Selected:
     • Particles collide slower (lower slope)
     • Some reactants remain; only some product is formed.

7. Increase Surface Area

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

8. Add Catalyst

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

Summary of Observations:

• Temperature Effects: Higher temperatures increase the kinetic energy of particles, leading to faster collisions and completion of the reaction, while lower temperatures slow the collisions down.
• Concentration Effects: Higher concentrations provide more reactant particles, resulting in more frequent collisions and higher reaction rates.
• Surface Area Effects: Increasing surface area allows for more exposure of reactant particles, facilitating quicker reactions, while decreasing surface area restricts the reaction.
• Catalyst Effects: Adding a catalyst speeds up the reaction by providing an alternative pathway for the reaction with a lower activation energy, enhancing the rate of product formation.
