Heats of Reaction: Interactive Simulation

This simulation runs in your browser. Try to predict the behavior when a parameter changes before using a slider to change that parameter.  A screencast below describes how to use this simulation.

Simulation: Heat of Reaction Temperature Dependence

Examine how heat of reaction changes with temperature. Adjust the temperature with the slider, and choose between three reactions to see how each heat of reaction changes with temperature.

Try to answer these questions before determining the answer with the simulation. We suggest that you write down the reasons for your answers.

  1. Does heat of reaction increase or decrease as temperature increases?
  2. Since enthalpies increase with temperature, why are the changes in heat of reactions with temperature small?
