Question

i What would happen to the concentration if the volume of the box doubled? Explain why in terms of particles.

Answer 1

the concentration will decrease

Step-by-step explanation:

this is due to the fact that concentration is the amount of particles in a specific volume. So by increasing the volume of the container, the overall concentration of the solution will decrease.

For example think of dilute squash in a small cup and in a bucket. Let's fill up the cup and bucket with 2 parts squash . when you have your small cup, you have 3 parts in total. In the cup your juice is more concentrated as you have more of the squash dissolved in the volume the ratio of water to juice is 1 : 2, so there is a higher concentration of squash in the cup. when you have your bucket, you have 7 parts in total. In the bucket your juice is less concentrated as you need more water to mix with the squash the ratio of water to juice is 5 : 2, so there is a higher concentration of water in the cup.

so in terms of particles, when you increase the volume by doubling it, the concentration of your solution will half, as the particles are occupying a bigger volume

Answer 2

Doubling the volume of a box would decrease the concentration of particles since the same number of particles would now be spread out over a larger volume. This reduction in concentration would likely result in a decrease in the rate of reaction, as fewer particle collisions would occur.

Step-by-step explanation:

When thinking about what would happen to the concentration of particles in a box if the volume doubles, it is important to consider the particle model of matter. If the volume of the box increases and the number of particles remains the same, the concentration, which is the amount of particles per unit volume, will decrease.

Concentration and rate of reaction are closely linked. Doubling the concentration of a reactant often leads to an increase in the rate of reaction because it increases the number of collisions between reactant particles; hence, if concentration decreases (as it would if the volume doubles while the particle number remains constant), we could expect the rate of reaction to decrease as well. Similarly, in terms of Coulomb's law, altering distances or charges changes the force between particles, much like changes in concentration affect reaction rates.
