Concept explainers
Interpretation:
When a gas is burned in an automobile engine, the method of converting and releasing of energy in the gasoline needs to be explained.
Concept introduction:
Gasoline is a fuel which is used in automobile engines.
Answer to Problem 56A
Some amount of energy produced in the combustion of gasoline is used for working of engine and the rest amount is lost as heat to the surroundings.
Explanation of Solution
According to law of conservation of energy, energy neither can be created nor be destroyed. It can be converted from one form to another form of energy.
Thus when gasoline is burnt in an engine, the energy released by it is converted into work and heat.
Some amount of energy produced be combustion of gasoline is used for working of engine and the rest amount is lost as heat to the surroundings.

- 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%.
