Question 1

For a particular process, q = –17 kJ and w = 21 kJ. Which of the following statements is false?

◦ Heat flows from the system to the surroundings.
◦ The system does work on the surroundings.
◦ ΔE = +4 kJ
◦ The process is exothermic.
◦ None of these are false.

Question 2

For the reaction H2O(l) → H2O(g) at 298 K and 1.0 atm, ΔH is more positive than ΔE by 2.5 kJ/mol. This quantity of energy can be considered to be:

◦ the heat flow required to maintain a constant temperature.
◦ the work done in pushing back the atmosphere.
◦ the difference in the H–O bond energy in H2O(l) compared to H2O(g).
◦ the value of ΔH itself.
◦ none of these are correct.
