Unformatted text preview: The coefficients are fairly big, but not unreasonable. 3. Calculate the H for the reaction. Is the reaction exothermic or endothermic? 4. Calculate the S for the reaction. Is there an increase or decrease in entropy? 5. Calculate the G for the reaction (assume the reaction takes place at 25 o C). Is this reaction spontaneous or non-spontaneous? 6. Explain the differences between the ground state and the excited state. How does an electron move to the excited state? What happens when an electrons returns to the ground state? 7. Why is the flame purple?...
