1. What 4 things does rate of reaction depend on ?

  • Surface area, volume, scientist themselves, gasses
  • Speed, amount of solution, sunlight, energy
  • Temperature, surface area, catalyst, concentration/ pressure (for gas)
  • Activation energy, volume of liquid, sound, temperature

2. What are biological catalysts ?

  • Biological catalysts — enzymes, speed up reactions in living things.
  • Sun
  • Plants
  • Trees

3. How does increase in concentration & pressure increase rate ?

  • Makes sense
  • If something increases then rate must too ?
  • Higher concentration equals same amount of particles in the same volume which increases the successful collisions. Similarly, pressure of the gas increasing means the same number of particles are in the smaller space. This also makes collisions more freq
  • Just cos it does tbf…

4. What does a catalyst do ?

  • Add 10 passing & 10 pace
  • All work by decreasing the activation energy by providing an alternate reaction pathway.
  • Speeds up reaction.
  • Heighten activation energy to slow reaction.

5. How can more successful collisions be achieved through rising temp ?

  • Increased temp just increases everything
  • Cos….
  • Increase temp = increased speed of particles = increase in frequency of collisions —> higher heat energy also = more successful collisions
  • More particles move about
  • Quicker innit
