(a) Find the equilibrium constant for following acid dissociation reaction at 25°C. Start your answer by writing the equation for Ka written with AG°. NH, + NH3 +H* Is your calculated equilibrium constant (Ka) consistent with the value given in the course handout? (b) Find K, for the reaction at 10 and 40°C. Discuss how temperature affects fractionation between NH,* and NH3. (c) NH3 is often called free ammonia as opposed to ammonium ion. While ammonia ions are relatively benign, free ammonia is known to be toxic for microbial growth at high concentration especially in high strength wastewater treatment. Briefly discuss about potential temperature effects on the toxicity in biological wastewater treatment.

(a) Find the equilibrium constant for following acid dissociation reaction at 25°C. Start your answer by writing the equation for Ka written with AG°. NH,* + NH3 +H* Is your calculated equilibrium constant (Ka) consistent with the value given in the course handout? (b) Find K, for the reaction at 10 and 40°C. Discuss how temperature affects fractionation between NH4* and NH3. (c) NH3 is often called free ammonia as opposed to ammonium ion. While ammonia ions are relatively benign, free ammonia is known to be toxic for microbial growth at high concentration especially in high strength wastewater treatment. Briefly discuss about potential temperature effects on the toxicity in biological wastewater treatment.
