You have a liquid mixture with a liquid mole ratio of 35% A and 65% B. After the mixture is heated to its boiling point, you find the mole ratio in the vapor is 70% A and 30% B. Which of the following statements best describes the change in composition of the components A and B from the liquid phase to the vapor phase?
A) Component A increases in concentration from the liquid phase to the vapor phase, while component B decreases.
B) Component A decreases in concentration from the liquid phase to the vapor phase, while component B increases.
C) Component A remains unchanged in concentration from the liquid phase to the vapor phase, while component B decreases.
D) Component A decreases in concentration from the liquid phase to the vapor phase, while component B remains unchanged.
