Chemostry Fundamentals

Definition

• Chemostry is a branch of chemistry focused on the study of chemical processes and reactions in relation to biological systems.

Key Concepts

1. Chemical Equilibrium:

   • State where the concentrations of reactants and products remain constant over time.
   • Forward and reverse reactions occur at the same rate.

2. Kinetics:

   • Study of the rate of chemical reactions.
   • Influences include temperature, concentration, and catalysts.

3. Reaction Mechanisms:

   • Step-by-step description of how reactants convert into products.
   • Involves intermediate species and transition states.

4. Thermodynamics:

   • Laws governing energy changes in chemical reactions.
   • Key terms include enthalpy, entropy, and Gibbs free energy.

5. Reagents:

   • Substances used to cause a chemical reaction.
   • Types include oxidizing agents, reducing agents, and catalysts.

Applications

• Drug development: Understanding reaction pathways is crucial for synthesizing pharmaceuticals.
• Environmental chemistry: Studying the impact of chemicals on ecosystems.
• Biochemistry: Exploring metabolic pathways and enzyme functions.

Techniques

• Spectroscopy: Analyzing substances based on how they interact with electromagnetic radiation.
• Chromatography: Separating mixtures into their components for analysis.
• Titration: Quantitative chemical analysis to determine the concentration of an identified analyte.

Important Theories

• Le Chatelier's Principle: If a system at equilibrium is disturbed, the system will adjust to minimize the disturbance.
• Arrhenius Equation: Relates temperature and reaction rate, showing how increasing temperature typically increases reaction rates.

Safety Considerations

• Proper handling and disposal of chemicals.
• Use of personal protective equipment (PPE) like gloves and goggles.
• Understanding Material Safety Data Sheets (MSDS) for chemical handling.
