Collision Theory

Question 1

How can collision theory be explained in terms of concentration?

Answer 1

According to collision theory, increasing the concentration of reactants means there are more particles in a given volume, so particles collide more often. This leads to a higher chance of successful collisions, increasing the rate of reaction.

Question 2

How can collision theory be explained in terms of pressure?

Answer 2

According to collision theory, increasing the pressure of a gas reaction compresses the particles into a smaller volume, so they collide more frequently. This raises the chance of successful collisions, which increases the reaction rate.

Question 3

How can collision theory be explained in terms of particle size?

Answer 3

According to collision theory, smaller particle size means a larger surface area, leading to more frequent collisions and a faster reaction rate.

Question 4

How can collision theory be explained in terms of temperature?

Answer 4

According to collision theory, increasing the temperature gives particles more energy and makes them move faster, leading to more frequent and more energetic collisions. This increases the chance of successful collisions, speeding up the reaction.

Question 5

How can collision theory be explained in terms of collision geometry?

Answer 5

According to collision theory, for a reaction to occur, particles must collide with the correct orientation (collision geometry). Even if they have enough energy, a reaction only happens if they are aligned properly, so effective collisions depend on both energy and geometry.
