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.
oops. When you INCREASE the pressure the volume DECREASES.
The other relationship is direct. In direct one variable goes up the other goes up. Or one goes down the other goes down.
Of course some don't have a relationship; i.e., one variable goes up or down and there is no change in the other.

Here is my personal opinion. I can't find anything especially wrong with what you've said; however, I don't think it is a good explanation. In my opinion you have simply rephrased the question and called that your answer. If I were grading your paper I wouldn't give you any credit for your answer; however, I'm not grading your paper. Your paper grader may agree with you completely.
how did i rephrase the question? what do you mean?
what is an inverse relationship?
one variable goes up and the other variable goes down.
Pressure-volume is inverse. When you INCREASE
To explain why reactant size and the rate of reaction have an inverse relationship based on the given graph, we need to understand the key concepts of reactant size and the rate of reaction.
Reactant size refers to the size of the particles or molecules involved in a chemical reaction. In this case, the reactant size is represented by the "size of marble chips" on the x-axis.
The rate of reaction, on the other hand, measures how quickly a reactant is consumed or how quickly a product is produced. It is represented by the "rate of carbon dioxide production" on the y-axis.
Looking at the graph, we see that as the size of the marble chips increases (moving from left to right on the x-axis), the rate of carbon dioxide production decreases (moving from top to bottom on the y-axis). This downward slope indicates an inverse relationship between the reactant size and the rate of reaction.
The reason for this inverse relationship is that larger particles have a smaller surface area compared to smaller particles. When a reaction occurs, it often takes place on the surface of the reactant particles. Therefore, larger particles have a smaller surface area available for the reaction to take place, leading to a slower rate of reaction.
In simpler terms, if you increase the size of the reactant (marble chips in this case), it takes more time for the reactant to dissolve or react because there is less surface area for the reactant to interact with the other substances involved. This results in a decrease in the rate of reaction.
In conclusion, based on the given graph, we can explain that reactant size and the rate of reaction have an inverse relationship. As the size of the marble chips (reactant size) increases, the rate of carbon dioxide production (rate of reaction) decreases.
