Question

Nitrogen gas is soluble in water. At temperature 293 K, the value of K_H is 76.48 k bar. How would the solubility of nitrogen vary (increase, decrease or remain the same) at a temperature above 293 K if the value of K_H rises to 88.8 k bar?

Answer 1

Solubility of gas is inversely proportional to the value of Henry's constant K_H. On increasing temperature, nitrogen gas becomes less soluble because its K_H value increases.
