Consider the reaction:
2 NO(g) + Br2(g) =2 NOBI(g)
A chemist placed 0.0322 mol of NO and 1.70 g of bromine (Br2) into a
sealed 1.00 L reaction vessel and then allowed the reaction to reach
equilibrium.
The pressure of the NOBR at equilibrium at 25.0°C is 0.444 bar. (R =
0.08314 L·bar/mol·K and MW of Br2 is 159.808 g/mol.)
Calculate the Kp.
