1. A student ran the following reaction in the laboratory at 304 K: 2NO(g) + Br2(g) 2NOBr(g) When she introduced NO(g) and Br2(g) into a 1.00 L evacuated container, so that the initial partial pressure of NO was 1.22 atm and the initial partial pressure of Br2 was 0.574 atm, she found that the equilibrium partial pressure of Br2 was 0.246 atm. Calculate the equilibrium constant, Kp, she obtained for this reaction. Kp =
