When 2.00 mol of NOCl(g) was heated to 225 degrees celcius in a 400L steel reaction vessel, the NOCl partially decomposed according to the equation 2 NOCl(g) -->2 NO(g) + Cl2(g). The pressure in the vessel after the reacton is 0.246 atm. (a) What is the partial pressure of each gas in the vessel after the reaction? (b) What precent of the NOCl decomposed?
