WebI. Sublimation occurs at a point in the transformation that occurs along a straight line from point A to point F. II. C and E represent points where the gas and liquid phases are in equilibrium. III. ∆Hvap can be measured at point B. IV. Molecules at point D have a greater average kinetic energy than those at. point F. WebTo determine the magnitude of the energy change, we must first convert the amount of Br2to moles. Then we can use ΔHvapas a conversion factor. 66.7 g Br2× (1 mol Br2/159.8 g Br2) × (15.4 kJ/1 mol Br2) = 6.43 kJ Because the process is exothermic, the actual value will be negative: ΔH = −6.43 kJ.
