- Reactions involve the transformation of starting materials (reactants) into products.
- Reactions can be classified as endothermic or exothermic depending on whether they absorb or release energy, respectively.
- Reactions can be sped up by catalysts, which lower the activation energy required for the reaction to occur.
- Reactions must satisfy the law of conservation of mass, meaning that the total mass of reactants must equal the total mass of products.

Enzymes are catalysts. This means that they are able to speed up chemical reactions. Which of the following statements is also true of enzyme catalysts?
Enzymes are specific in their actions, meaning they typically catalyze only one type of reaction or a few closely related reactions.
Which of the following combustion reactions is balanced correctly?
The correct answer is: C5H12 + 8O2 5CO2 + 6H2O.
Which of the following statements about enzymes is not true A are catalysts B almost all enzymes are proteins C operate most efficiently at optimum pH D destroyed during chemical reactions?
D. destroyed during chemical reactions. Enzymes are not destroyed during chemical reactions; they remain unchanged and can be reused multiple times.
Why the reactions of high order are rare?
Reactions of high order are rare because they involve multiple reactant molecules coming together simultaneously in the correct orientation and energy to undergo a reaction. This makes high order reactions less likely to occur due to the increased difficulty of all reactants colliding in the correct manner at the same time. Additionally, high order reactions tend to have lower reaction rates and are often less favorable thermodynamically.
