Question

A gas mixture contains 13.2 mol of NO and 5.55 mol of Br2.

(a) Compute the mole fraction of NO in the mixture.

XNO =

(b) The mixture is then allowed to stand, and the NO starts to react with the Br2 to give NOBr: 2NO(g) + Br2(g) 2NOBr(g)

At a certain point in the reaction, 2.40 mol of NOBr is present. Determine the mole fraction of NO in the new mixture. XNO =
