3. Now use the following pKa to verify your answer in question 1. Did you get the answer correct? Explain why or why not. What does the value of the pKa mean in terms of acid strength? 4. Here are the pKa values for Question 2. Did you get the answer correct in which direction the equilibrium lies for each reaction? Explain why or why not. H₂O, PK, 15.7 NH, pK 33 CH, PK > 55 (Hint: You may want to first identify your acid and base followed by comparing the pKa values of your acid and conjugate acid). a. b. pKa H,O = 15.7, NH =9.8, NH = 33 NH, + HO D NH + OH NH + H₂O D NH₂ + OH

Question
Can you explain these follow up questions using my answers to 1 and 2
1. Circle which of the following you would predict to be the strongest acid? Using your understanding from Chapter 7, explain your reasoning. H₂O The strongest acid is H2O because as we move along the period the acidity increases, the electronegativity of the central atom increases which increases their acidity. a. 2. For the acid-base reactions given, draw out the full reaction using Lewis structures and curved arrows to indicate how the reaction takes place. Predict whether the equilibrium position would lie to the right or the left. Explain your reasoning. 从一 b. NH3 + H₂O NH4+OH equilibrium shift in backward H H NH3 TH 80 NH₂ + H₂O NH3 +OH equilibrium shift in forward 00 84 4 CH4 12 # + 8 H :D TH (
