Describe how you can determine the total change in enthalpy and activation energy from the diagram, and if each is positive or negative.

ASSIGNMENT

Part 1: Describe how you can determine the total change in enthalpy and activation energy from the diagram, and if each is positive or negative.

Part 2: Describe how the curve will look if the reaction was exothermic. Be sure to mention changes in the potential energies of the reactants and products and the sign changes of the enthalpy.

During an experiment, ice and water were placed in a perfectly insulated thermos flask at 0 °C. Describe this system when it phase reaches equilibrium.

Explain how the solubility of water is useful in maintaining various life processes.
