Problem

For the gas-phase equilibrium

2\,\text{NOBr}(g)\rightleftharpoons 2\,\text{NO}(g)+\text{Br}_2(g)

at 500 K, the equilibrium constant is

K_p = 1.2

. A rigid container is charged with

P_{\text{NOBr}} = 0.800\,\text{atm}

and no products. What is the equilibrium partial pressure of Br

_2

? a)

0.34\,\text{atm}

0.27\,\text{atm}

0.14\,\text{atm}

0.48\,\text{atm}
