Explain Ammonia and hydrogen chloride gases react to form solid ammonium chloride. A 10.0 L reaction flask contains ammonia at 0.444 atm and 22°C, and 146 mL of hydrogen chloride gas at 7.50 atm and 271 K is introduced.
Subsequent to the reaction occurs and the temperature returns to 22°C, Explain what is the pressure inside the flask? Neglect the volume of the solid product.
