Chemical Kinetics and Reaction Rates

Factors Influencing Reaction Velocity

• Rate Equation: V = k · [A]^a · [B]^b
• Temperature: The Arrhenius Law: k = k₀ · e^{-E_a / (R · T)}
• Concentration and Pressure: P · V = n · R · T
  P = (n · R · T) / V → n / V = concentration
  P = [X] · R · T
• Standard State and Physical State:
  • Solid: Few collisions result in slow reactions. The level of division is key; more particles mean a greater impact surface.
  • Liquid: Average collision frequency results in average reaction speeds.
  • Gas: Many collisions result in faster reactions.
• Catalysts: Positive catalysts increase speed. Negative catalysts (inhibitors) slow it down. Catalysts do not change thermochemical quantities (ΔH, ΔG, ΔS...), the quantity of product, or

The Importance of Sustainable Energy Production

Energy production is a fundamental process for most human activities on Earth. Its use in sectors such as industry, commerce, transport, telecommunications, and a wide range of agricultural and domestic services has compelled us to focus our attention on ensuring a continuous supply to meet our increasing demands. Nowadays, the main source of energy is fossil fuel. Coal, oil, and natural gas could be exhausted soon; therefore, scientists are seeking new alternative energies.

Renewable vs. Non-Renewable Energy

Basically, energy can be divided into renewable and non-renewable energy. Renewable energy is produced using natural resources that are constantly replaced and will never run out. There are... Continue reading "Renewable Energy Sources: Benefits and Challenges" »
