effects of concentration, pressure & surface area

Question 1

what is the relationship between increasing pressure / concentration?

Answer 1

• more particles per unit volume
• collide with greater frequency
• higher frequency of successful collisions

Question 2

describe the change in maxwell boltzmann distribution curve for increasing pressure / concentration.

(peak, shape, Emp, mean energy, curve, num. of particles)

Answer 2

• peak at same energy, same shape
• Emp & mean energy stays same
• higher curve -> more area (more particles have energy > Ea)

Question 3

what is the relationship between surface area and collisions of particles?

Answer 3

larger surface area = more successful collisions to occur more frequently
