Unformatted text preview: equilibrium, reaction has to shift to left to produce more H 2 ( g ) and Br 2 ( g ). Assume that the change in [Br 2 ] is x mol/L then: H 2 ( g ) + Br 2 ( g ) 2HBr ( g ) K c = 0.293 I 0 0 1.00 M C +x +x 2x E x M x M 1.002x M Using the equilibrium constant expression: K c = (1.00 2 x ) 2 x x = (1.00 2 x ) 2 x 2 = 0.293 So: x = 0.394 M . Answer is C....
