3.1.5.4. effect of concentration and pressure

• what happens when the concentration of a sample is increased?

  more molecules of a substance occur in the same volume so they are packed closer together
• how does the concentration being increased reflect on the rate of collisions?

  collisions between molecules are more likely and the chances of a collision occurring with E≥EA increases - rate of reaction increases
• what happens when the pressure increases?

  the same effect as concentration as molecules are packed closely together into a smaller volume
• how is the increase reflected in the MB distribution?
