Rates of Reaction

4. The substances formed as a result of a chemical reaction when reactants are transformed.
8. The total area of the exposed surface of an object or substance.
9. The substances that participate in a chemical reaction, undergoing transformation into products.
10. A substance that increases the rate of a chemical reaction by lowering the activation energy required for the reaction to occur, without being consumed in the process.
12. The speed at which a chemical reaction occurs, often measured in terms of how quickly reactants are converted into products.
13. A measure of the degree of hotness or coldness of an object.
14. The physical interaction or contact between particles or objects, which can be crucial in chemical reactions.
15. The measure of the amount of a substance (usually a solute) present in a given volume of a solution.

1. When particles are available to react, they are considered...
2. Related to motion or the energy of particles in a system.
3. The amount of space occupied by an object or substance.
4. A tiny, discrete unit of matter, which can refer to atoms, molecules, ions, or subatomic particles.
5. The amount of energy required to start a chemical reaction.
6. A chemical reaction in which the reactants collide with sufficient energy, and at the correct orientation.
7. process in which one or more substances (reactants) change into new substances (products) due to chemical interactions.
11. The specific arrangement or positioning of particles or objects in a particular direction or relative to one another.
