Question

A student ran the following reaction in the laboratory at 290 K:

2NO(g)+Br2 (g) <---> 2NOBr (g)

When she introduced NO (g)  0.141 moles of and 0.121 moles of Br2 (g) into a 1.00 liter container, she found the equilibrium concentration of Br2(g) to be 0.0665 M.

Calculate the equilibrium constant, Kc she obtained for this reaction.

Kc=
