The solubility of a gas in a liquid increases with increasing pressure. to understand the above statement, consider a familiar example: cola. in cola and other soft drinks, carbon dioxide gas remains dissolved in solution as long as the can or bottle remains pressurized. as soon as the lid is opened and pressure is released, the co2 gas is much less soluble and escapes into the air. the relationship between pressure and the solubility of a gas is expressed by henry's law: s=kp, where s is concentration in m, k is the henry's law constant in units of mol/(l⋅atm), and p is the pressure in atm. note: since temperature also affects the solubility of a gas in an liquid, the henry's law constant is specific to a particular gas at a particular temperature. the following table provides some information on carbon dioxide solubility in water. s (mol/l) p (atm) k (mol⋅l−1⋅atm−1) t (∘c) 3.80×10−2 1.00 20.0 6.60×10−2 20.0 1.00 3.50×10−2 25.0 part a what is the henry's law constant for co2 at 20∘c?

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
