At 320 K and 16 atm, the molar volume of ammonia gas is about 10% less than the molar volume of an i — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

the actual volume of ammonia being less than the ideal volume (z < 1) indicates a negative deviation. this occurs because the intermolecular attractive forces (the 'a' parameter) between the highly polar ammonia molecules are significant at 16 atm, causing the molecules to pull closer together.
