Question 1
Classify each of the following processes as spontaneous or nonspontaneous.
I. | H2O(l) → H2O(g) | T = 25°C, vessel open to atmosphere with 50% relative humidity |
II. | H2O(s) → H2O(l) | T = 25°C, P = 1 atm |
◦ I is nonspontaneous and II is spontaneous.
◦ I and II are both spontaneous.
◦ I and II are both nonspontaneous.
◦ I is spontaneous and II is nonspontaneous.
Question 2
The reaction A(
g) → B(
g) is spontaneous under standard conditions. Which of the following statements must be true?
I. | The reaction B(g) → A(g) is nonspontaneous under standard conditions. |
II. | A(g) will be completely converted to B(g) if sufficient time is allowed. |
III. | A(g) will be completely converted to B(g) rapidly. |
◦ none of these
◦ I
◦ I and II
◦ I, II, and III
