Some NOCl(g), intially at 1.000 atm, is placed in an empty reaction vessel. At equilibrium, the total pressure is 1.135 atm.

Some NOCl(g), intially at 1.000 atm, is placed in an empty reaction vessel. At equilibrium, the total pressure is 1.135 atm. Assuming the partial pressures are in atmospheres, what is Kp for the reaction below?

2 NOCl(g)   ⇌ 2 NO(g) + Cl2(g)

Enter your answer accurate to 3 significant figures.
