Temperature
The peak of higher temp. is always further to the right and lower than the peak of lower temp. Higher temp: ↑ average kinetic energy of reactant particlesCollision frequency ↑Proportion of reactant particles that have energy greater than Ea ↑Successful collision frequency ↑
파일
Larger SA (smaller size):
• ↑ no. of reactant particles available for immediate rxn
• Collision frequency ↑
• Successful collision frequency ↑
Higher concentration:
• ↑ the no.of reactant particles at a certain volume
• Collision frequency ↑
• Successful collision frequency ↑
• *If [limiting reactant] ↑, both the rate and product amount ↑
Catalysts lower the Ea by providing an alternative reaction pathway
Catalysts increase the proportion of particles that have energy greater than the minimal energy required for successful collision (Ea)
• Successful collision frequency ↑
