- Summarize the relationship between pKa and base strength by completing the followingsentences: a. For a given base, the higher the pKa of its conjugate acid, the stronger or weaker the base. b. For a given base, the lower the pKa of its conjugate acid, the stronger or weaker the base.Give typed full explanation not a single word hand written otherwise leave it How do we know that (d) is the strongest acid? Please explainExplain which is stronger acid
- can you explain why second more is more acidic than 3rdMay you answer this with an explainationFor NH3 (ammonia) and H2O (water)... a. Use curved arrows to show the most likely acid-base reaction, and draw the resultingproducts. (Hint: First decide which is the stronger acid, and which is the stronger base.) b. Mark each curved arrow with a positive (bond-breaking) or negative (bond-forming) numberindicating the energy change associated with that arrow (in pKa units). c. Calculate Hrxn and write this number above a set of reaction arrows that indicate whichdirection is downhill/favorable (in the example, the reaction is downhill to the right). d. Sketch an energy diagram for the reaction. e. Is your energy diagram consistent with the fact that, in this case, the most likely acid-basereaction is endothermic?
