A scientist measures the standard enthalpy change for the following reaction to be -79.6 kJ:

2HBr(g) + Cl2(g)2HCl(g) + Br2(g)

Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of Br2(g) is: kJ/mol.

How do you form a Z-enolate over an E-enolate? Does it have to do with kinetics vs thermodynamics or just starics, or both? What is the reasoning behind this selectivity?
