1.Use the graph below to explain why reactant size and the rate of reaction is considered an inverse relationship.
(i cannot attach pictures so i will describe the graph)
the graph shows a line that goes in a downward slope, the y xis title says: "rate of carbon dioxide production", and the x axis says "size of marble chips"
My answer:
because if you increase the size of the particle, the reactant rate decreases because it takes more time to dissolve something big than it takes to dissolve something small.
To explain why reactant size and the rate of reaction are considered an inverse relationship using the provided graph, follow these steps:
1. Start by understanding the variables on the graph. The y-axis represents the rate of carbon dioxide production, which is a measure of how quickly carbon dioxide is being produced as the reaction proceeds. The x-axis represents the size of the marble chips, which refers to the particle size of the reactant.
2. Note that the line on the graph has a downward slope. This indicates that as the size of the marble chips increases (moving towards the right along the x-axis), the rate of carbon dioxide production decreases (moving downwards along the y-axis).
3. Based on this graph, we can conclude that as the size of the marble chips increases, the rate of reaction decreases. This inverse relationship suggests that larger reactant particles result in slower reaction rates.
Now, let's explain the reasoning behind this inverse relationship:
When the reactant particles are larger, they have a smaller surface area-to-volume ratio. The surface area of a particle is the area available for the reactive substances to come into contact with each other and facilitate the reaction. As the particle size increases, the surface area decreases in proportion to the overall volume.
Because reaction rates depend on the frequency of successful collisions between reactant particles, a smaller surface area limits the opportunity for effective collisions. Therefore, more time is required for the reactant particles to come into contact and react, resulting in a slower reaction rate.
In summary, from the provided graph, when the size of the marble chips increases, the rate of carbon dioxide production decreases, indicating an inverse relationship between reactant size and the rate of reaction.
