Problem Details

Hydrogen and iodine gases react to form hydrogen iodide gas as follows: 

H2 (g) + I2 (g) → 2HI (g) 

At a certain temperature and pressure 1.4 L of H 2 reacts with 1.4 L of I 2. If all the H2 and I2 are consumed, what volume of HI, at the same temperature and pressure, will be produced?
