Part I : Answer the following showing all work and/or in a clear and concise manner.<br> <br> <br> 1. What is the difference between temperature and heat?<br> <br> <br> <br> <br> 2. What is the definition of activation energy (E<sub>ac</sub>)? <br> <br> <br> <br> <br> 3. Potential energy of the reactant (PE<sub>r</sub>) is _________ compared to the potential energy of the product (PE<sub>p</sub>).in an Exothermic rxn.<br> <br> <br> 4. ___________________ is the average kinetic energy of all the particles in a substance. <br> <br> <br> 5. State the two parts to "our" definition of the 2nd Law of Thermodynamics.<br> <br> <br> <br> <br> <br> 6. Absolute zero is the condition where __________________________. The condition of absolute zero is _________________ and _________________.<br> <br> <br> 7. Entropy is the measurement of _______________________________<br> <br> <br> 8. If a system (for example water) has a delta H that is "-", the system (i.e. water) would be releasing or absorbing energy/heat? Circle correct answer.<br> <br> <br> 9. What is a spontaneous reaction in Thermo? What thermodynamic property deals with it (it needs to be negative for the reaction to be spontaneous.)<br> <br> <br> <br> <br> 10. What two "ways" can a reaction stop (i.e. no more product is made)?<br> <br> <br> <br> 11. deltaG, Gibbs Free Energy change is composed of two other Thermodynamic properties. What are these properties. <br> <br> <br> <br> 12.Can spontaneous reactions be endothermic reaction also, yes or no? Explain.<br> <br> <br> <br> <br> <br> <br> 13. How does the concept of Entropy affect or explain one or more of the conditions for absolute zero?<br> <br> <br> <br> <br> <br> 14a. Explain the difference between a Relative temperature scale (i.e. Celsius) and Absolute temperature scale (i.e. Kelvin). <br> <br> <br> <br> <br> <br> 14b. Someone stated that "energy was lost in the chemical reaction". State if you agree or disagree with that statement. Justify your answer using your knowledge of Thermo. <br> <br> <br> <br> <br> <br> 14c. What type of energies compose Enthalpy?<br> <br> <br> <br> <br>
