for a project i had to make cards with words and then an example of those words, and i've done almost all of them, but I have a few words I need examples for
activation energy
activation energy
activated complex
elementary reaction
To find examples for the words you mentioned, you can follow these steps:
1. Search for a reliable source: Look for reputable scientific websites, textbooks, or journals that provide information on chemical reactions and kinetics. This will ensure that the examples you find are accurate and trustworthy.
2. Understand the concept: Before finding examples, it is important to understand the definitions of the terms you mentioned. Here's a brief explanation for each:
a. Activation energy: Activation energy is the minimum amount of energy required for a chemical reaction to occur. It represents the energy barrier that reactant molecules must overcome to convert into products.
b. Activated complex: An activated complex (or transition state) is an intermediate arrangement of atoms formed during a chemical reaction. It exists at the highest point on the reaction energy diagram and is short-lived. It is followed by the formation of products or the reformation of reactants.
c. Elementary reaction: An elementary reaction is a single step reaction that involves the collision of reactant molecules, leading to the formation of products. It is the smallest unit of a reaction mechanism.
3. Find examples for each term:
a. Activation energy example: Consider the reaction of hydrogen gas (H2) with oxygen gas (O2) to form water (H2O). The energy required to break the H-H and O=O bonds and form the new H-O bonds represents the activation energy.
b. Activated complex example: In the reaction between hydrogen (H2) and chlorine (Cl2) to form hydrogen chloride (2HCl), the activated complex represents the temporary formation of H-Cl bonds during the reaction.
c. Elementary reaction example: One example of an elementary reaction is the decomposition of hydrogen peroxide (2H2O2) into water (2H2O) and oxygen gas (O2), which occurs in a single step.
Remember to cite the sources where you find these examples to ensure academic integrity and accuracy for your project.
