rates of reaction

• temp increased means that particles have more kinetic energy so collide more often increasing rate of reaction
• concentration increased means more particles in same volume so more frequent collisions reaching activation energy quicker increasing rate of reaction
• if pressure increase, volume decreases meaning more frequent collisions reaching activation energy quicker resulting in increase rate of reaction
• if surface area increases, more particles are able to collide resulting in more successful collisions leading to activation energy reached quicker and rate of reaction increases
