The amount of heat emitted during the condensation of 65.6 g of isopropyl alcohol at 25 ° C is to be calculated. Concept introduction: Heat of condensation is the amount of heat released to condense one mole of vapor into liquid. Heat of condensation is opposite to the heat of vaporization. Since heat is released during condensation, condensation is an exothermic process. Hence, the value of heat of condensation is written with a negative sign. The heat of condensation is used to calculate the amount of heat released to condense a given amount of liquid at a given temperature. For this, heat of condensation is used as a conversion factor between the amount of heat required to condense a liquid and moles of the liquid.

need help please and thanks dont understand only need help with C-F Learning Goal: As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT. The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7). Part A - Difference in binding free eenergies Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol. The margin of error is 2%. Part B - Compare difference in free energy to the thermal…
