This virtual manipulative will allow you to watch a reaction proceed over time. You can vary temperature, barrier height, and potential energies to note how total energy affects reaction rate. You will be able to record concentrations and time in order to extract rate coefficients.
Additionally you can:

• Describe on a microscopic level, with illustrations, how reactions occur.
• Describe how the motion of reactant molecules (speed and direction) contributes to a reaction happening.
• Predict how changes in temperature, or use of a catalyst will affect the rate of a reaction.
• On the potential energy curve, identify the activation energy for forward and reverse reactions and the energy change between reactants and products.
• Form a graph of concentrations as a function of time, students should be able to identify when a system has reached equilibrium.
• Calculate a rate coefficient from concentration and time data.
• Determine how a rate coefficient changes with temperature.
• Compare graphs of concentration versus time to determine which represents the fastest or slowest rate.
