Question

6) The Henry's law coefficients for various NO and sulfur species are given below. Species H (M atm Species H (M atm) NO 1.9 x 10 SO2 1.2 NO2 1x 10-2 H2S 0.087 HNO3 2.1 x 10 COS 0.022 Is NO or NO2 more soluble in water? 7) How many ozone molecules would you expect to be formed as a product of CO oxidation in a low-NOx environment?

Answer 1

Question - 6 We have Henry's law equation as P = KHX where I constant p KH x partial pressure of gas Henry's law. male praction of gas dissolue in the solvent ou wo ng boven KHO I so Higher the Henry's constant lover the solubility. As in giuen question No has is Henry's constant than NO2 Bo No will be more soluble in mater. Question-7.
