Consider the system 4NH 3 ( g ) + 3 O 2 ( g ) ⇌ 2 N 2 ( g ) + 6 H 2 O ( l ) Δ H = − 1530.4 kJ (a) How will the amount of ammonia at equilibrium be affected by 1. removing O 2 ( g )? 2. adding N 2 ( g )? 3. adding water? 4. expanding the container at constant pressure? 5. increasing the temperature? (b) Which of the above factors will increase the value of K ? Which will decrease it?

Solution Summary: The author explains Le Chatelier's principle: if at equilibrium, any change in temperature, concentration or pressure is applied to a system, the shift in equilibrium takes place to counteract the change.
You have started a patient on a new drug. Each dose introduces 40 pg/mL of drug after redistribution and prior to elimination. This drug is administered at 24 h intervals and has a half life of 24 h. What will the concentration of drug be after each of the first six doses? Show your work
a. What is the concentration after the fourth dose? in pg/mL
b. What is the concentration after the fifth dose? in pg/mL
c. What is the concentration after the sixth dose? in pg/mL
