Nitric Oxide and Bromine Were Allowed to React in a Sealed

Question 75

Question 75

Multiple Choice

Nitric oxide and bromine were allowed to react in a sealed container. When equilibrium was reached PNO = 0.526 atm, Nitric oxide and bromine were allowed to react in a sealed container. When equilibrium was reached P<sub>NO</sub> = 0.526 atm,   = 1.59 atm, and P<sub>NOBr</sub> = 7.68 atm. Calculate K<sub>p</sub> for the reaction. 2NO(g)  + Br<sub>2</sub>(g)  ⇄ 2NOBr(g)  A) 7.45 × 10 <sup>−</sup><sup>3</sup> B) 0.109 C) 9.18 D) 91.8 E) 134 = 1.59 atm, and PNOBr = 7.68 atm. Calculate Kp for the reaction.
2NO(g) + Br2(g) ⇄ 2NOBr(g)


A) 7.45 × 10 −3
B) 0.109
C) 9.18
D) 91.8
