Kinetics in Therm Systems

Postby Denja1H » Thu Mar 14, 2024 11:25 am

How do kinetics vary in different types of thermodynamic systems? Does speed change at all or reaction steps?

reaction rates may change depending on the system's characteristics (concentration, temperature, pressure, and catalysts can all affect the speed and reaction steps in various thermodynamic systems).

kinetics is about how fast a reaction happens, while thermodynamics is about whether the reaction can happen at all. In closed systems where nothing goes in or out, or open systems where stuff can come and go, the speed of reactions can change. things like temperature, concentration, and the presence of catalysts can all affect how quickly reactions go. regardless how fast or slow, the overall feasibility of a reaction, determined by thermodynamics, stays the same. while the speed of individual steps in a reaction might vary, whether the reaction happens or not, that's a thermodynamics thing.

Hello,
Thermodynamics focuses on the energetics of the products and the reactants, whereas kinetics focuses on the pathway from reactants to products.

Kinetics in closed systems involve changes in temperature, pressure, and concentration. Reaction steps typically stay the same unless there's a change in reaction conditions such as a change in temperature or if there’s a catalyst

The speed of a reaction in an open system can be changed by things like temperature and pressure but also by the rate of transfer of reactants and products in and out of the system. For open systems mass transfer can make reaction steps different. Like if the rate of transfer of reactants is slower than the reaction rate, the reaction rate can get slowed down by mass transfer, resulting in different reaction steps.

Kinetics in a thermodynamic system can vary based on reaction mechanism, temperature, concentration, pressure, catalysts, surface area, and the chemical nature of the reactants.

The characteristics determine the rates of the equation itself.
