Question: What happens to the equation ΔH = ΔU + ΔVp if the change in pressure is very small?
Answer Options:
Then, ΔVp = V, so we can assume ΔH = ΔU + V
Then, ΔU >> ΔVp, so we can assume ΔH = ΔU
Then, ΔVp = Δp, so we can assume ΔH = ΔU + Δp
Then, ΔU << ΔVp, so we can assume ΔH = VΔp
Answer: Then, ΔU >> ΔVp, so we can assume ΔH = ΔU
Question: When comparing the different storage materials for fuels, which of these statements is FALSE?
Answer Options:
Li-ion batteries have the lowest energy density
Hydrogen has the highest specific energy, but its energy density is quite low
LP gas and gasoline have the same specific energy and thus are equally well-suited as fuels for a vehicle
Carbohydrates have a lower specific energy than hydrocarbon fuels, but a higher energy density due to being a solid
Answer: LP gas and gasoline have the same specific energy and thus are equally well-suited as fuels for a vehicle
Question: The combustion of octane is an exothermic reaction. Which statement is true for an exothermic reaction?
Answer Options:

It consumes heat because the reactants have a higher energy than the products
It consumes heat because the reactants have a lower energy than the products
It releases heat because the reactants have a higher energy than the products
Answer: It releases heat because the reactants have a higher energy than the products
Question: We saw in the calorimeter experiment that the combustion of a fuel is exothermic. What can you then say about the formation of a fuel?
Answer Options:
You cannot tell without performing an experiment
The reaction for formation of the fuel is the same, so it is also exothermic
The reaction for formation of the fuel is the opposite, so it is endothermic
The reaction for formation of the fuel is not related to the combustion
Answer: The reaction for formation of the fuel is the opposite, so it is endothermic
Question: How would you write the conversion reaction from oil to biodiesel?
Answer Options:

oil + alcohol + catalyst → biodiesel
oil + catalyst → biodiesel + glycerol + alcohol
Answer: oil + alcohol + catalyst → biodiesel + glycerol + catalyst
