4. 2NOBr <-----> 2NO + Br2
If 0.234 moles of NOBr, 0.336 moles of NO, and .350 moles ofBr2 are at equilibrium in a 17.9 L container at 455 K, the value ofthe equilibrium constant, Kp, is ______.
5. A student ran the following the reaction in the laboratoryat 584 K:
CO + Cl2 <-----> COCl2
When she introduced CO and Cl2 into a 1.00 L evacuatedcontainer, so that the initial partial pressure of CO was 2.78 atmand the initial partial pressure of Cl2 was 1.72 arm, she foundthat the equilibrium partial pressure of COCl2 was 1.38 atm.
Kp= ______
