I'm trying to figure out how to calculate K=concentration of products / contractions of reactants. Can someone help?

Week 2 - Predicting Direction of AB Reactions Worksheet Using pka to Peedist Reaction Direction To determine whether reactants or products are favored in an acid base reaction, follow these steps | Determine the molecule that will act as the acid on both sides of the equation 2. Locate most acidic proton and look up the pk. for each acid using a table 3. The reaction will favor the side of the reaction where the molecule with the highest pk is protonated + + OH HO D EXAMPLE For the reaction above, which two compounds are the acids? A CD Using the pK, chart, estimate the pK, for each of these two compounds Remember, pk. values are similar for functional groups in different molecules A=20-24 D=4 Is the pK, larger for the acid on the left or right side of the reaction? Are products or reactants favored? on the left the pka is larger The reactants are favored. Remember, each pK, unit is approximately a factor of 10 for the K (equilibrium constant) Predict the K for this reaction K concentration of products concentration of reactants - Predict the equilibrium constant for this reaction would be large 1) would be small would be about 1 Week 2 - Predicting Direction of AB Reactions Worksheet Using pka to Peedist Reaction Direction To determine whether reactants or products are favored in an acid base reaction, follow these steps | Determine the molecule that will act as the acid on both sides of the equation 2.
