Question: When 2 mol of NOCl was heated to 225 C in a 400 L steel reaction vessel the NOCl partially decomposes according to the equation:
2NOCL -----> 2NO + Cl2
the pressure in the vessel after the reaction is 0.246 atm.
What is the partial pressure of each gas (NO, Cl2, NOCl2)?
What % percent of NOCl decomposes?
