Phet reactions
WebSketch and analyze graphs showing changes in reactant and product concentrations as reactions proceed towards equilibrium; State the characteristics of a system at equilibrium. Use a potential energy diagram to determine whether reactants or products are favored during a reaction. WebWatch a reaction proceed over time. How does total energy affect a reaction rate? Vary temperature, barrier height, and potential energies. Record concentrations and time in order to extract rate coefficients. Do temperature dependent studies to extract Arrhenius parameters. This simulation is best used with teacher guidance because it presents an …
