What kind of reaction does the conversion of a to b represent? (cid:3) What kind of reaction does the conversion of a to b represent? (cid:3) (cid:3) (cid:3) Which of the following statements is not true? (cid:3) (cid:3) (cid:3) In polar reactions, a nucleophile reacts with an electrophile. A half-headed curved arrow shows the movement of an electron pair. Using the bond dissociation energies given, calculate dh for the following reaction. Which of the following expressions summarizes the correct relationship between the free energy change, dg , and the equilibrium constant, keq? (cid:3) Keq > 1 when dg > 0 (cid:1) (cid:2) Keq > 1 when dg < 0 (cid:3) (cid:3) Which of the keq corresponds to the most negative value of dg ? (cid:3) Which reaction has a positive dg , assuming that entropy changes are negligible compared to enthalpy changes? (cid:1) (cid:2) In which reaction is keq > 1? (cid:3)
