A chamber contains both Y and Y·6H2O at equilibrium. Its water vapour pressure is then increased by 25% without changing temperature. What are the new relative humidity and the initial direction of the hydrate reaction?
Options:
Answer:
B
Solution:
Initially, pH2O=(6.40×10-11)1/6=0.020 atm. Immediately after the increase, pH2O=1.25(0.020)=0.025 atm.
The new relative humidity is 100(0.025/0.050)=50%.
The dehydration quotient becomes (1.25)6Kp>Kp, so the reaction initially proceeds in reverse.
Water is absorbed to form the hydrate, giving option (b).
