• what 3 things increase rate of reaction and how

  pressure, surface area and concentration because particles collide more frequently
• how does temperature increase rate of reaction

  parties move faster. collide more frequently and with more energy, most likely to be successful
• how does catalyst increase rate of reaction

  reduce activation energy, collision more likely to be successful
• what do increasing temperature favour

  the enothermic reaction as heat is needed for it
